The TC74LCX125FT(EK2, M) is a high-performance low power single 4-Channel non-inverting buffer, driver, receiver and transceiver logic device. It belongs to the Logic - Buffers, Drivers, Receivers, Transceivers family.

It is designed to interface 5-V TTL to Logical Interface (L Level) and is bidirectional. It is guaranteed to withstand a 5V VOH minimum and a 2V VIL maximum in the normal operating environment of 0-70℃. The device operates from a single 4.5V to 5.5V VCC supply with an ICC MAX of 11mA. These features make it ideal for use in applications where low power consumption and low voltage operation are required.

TC74LCX125FT(EK2,M) has four full TTL-compatible channels with 30ns typical propagation delay time. Each channel consists of a passive pull-up resistor Rsupply of 5V. Two enable (E1 and E2) inputs per 4-channel enable or disable the output stage. The enable pin has TTL compatible thresholds. When enabled, the enable input in each channel overrides the channel outputs, forcing them to a high impedance state.

The E1 enable pin has an active low logic, and the E2 enable pin has an active high logic. The enable inputs are shared by all four channels such that enabling one input will enable all outputs. When the E1 & E2 enable inputs are both high, all outputs are enabled. When E1 & E2 enable inputs are both low, all outputs are in high impedance state. Thus, an active low “enable” signal can be used to enable or disable all outputs simultaneously.

TC74LCX125FT(EK2,M) also has a power supply enable (V SUPPLY) to enable or disable the entire device. When V SUPPLY is low, all output stages are in a disabled state, regardless of the state of their Enables lines. When V SUPPLY is high, the outputs will follow the logic state at their respective input pins, conditioned by their Enable pins.

The TC74LCX125FT(EK2,M) has a fully differential output stage and is designed for use in low power systems with a logic interface. With a quiescent supply current of only 11mA, it is ideal for applications that require a low power/low voltage solution. It also provides an architecture for input/output with combination for logic levels and drive capabilities.

TC74LCX125FT(EK2,M) is designed such that it can handle voltages up to 5V and is unidirectional in nature. It is suitable for a wide variety of applications, including in systems that require data and signal translation, as well as at the interface to analog devices like. It is suitable for use in medium speed buses and a variety of interface tasks.

TC74LCX125FT(EK2,M) comprises of four active low E, input stages, a differential output stage, and a power supply enable (V SUPLY). The E inputs are connected to the channel inputs, allowing users to turn on/off their control signals. The four outputs are connected to the open drain stages and they, in turn, are connected to the four open-drain stages of the output. The V SUPPLY signal allows users to turn on/off all outputs by a single signal.

TC74LCX125FT(EK2,M) operates at an interface voltage range of 4.5-5.5V. The outputs of the device are subjected to a 2V VIL maximum in the normal operating environment of 0-70°C. This ensures device operations are reliable even in sub-optimal climates. The device also has a 5V VOH minimum, allowing it to interface with low voltage interface circuits.

In conclusion, TC74LCX125FT(EK2,M) is a high-performance low power single 4-channel non-inverting buffer, driver, receiver and transceiver logic device for interface between 5V TTL and logical interface (L Level). It belongs to the family of logic buffers, drivers, receivers and transceivers and is suitable for a variety of applications that require low-voltage, low-power solutions. Its features make it ideal for applications requiring compatibility with a wide range of voltage levels.
