The TC74LCX373FT(EL) is a member of the TC74LCX logic family, specifically the latches family. It is an integrated logic device containing three low power Schottky Disable buffers. It provides high performance parallel data exchange and powerful long line buffering capabilities. It is useful in a wide array of applications, such as buses, memory systems, and peripheral controllers.

Application fields

The TC74LCX373FT(EL) is used in increasingly diverse applications. It is frequently employed in applications where long transmission paths are needed, such as data buses. Its on-chip Schottky Disable buffers allow signal propagation among multiple devices without loading, making it ideal for use in multi-drop buses and in many types of test and measurement systems.

It is also commonly used in memory systems such as random access memories (RAMs) and various types of memories, as well as in a variety of motor controllers. Additionally, the TC74LCX373FT(EL) is becoming increasingly important in digital communication systems such as Ethernet, ATM, and packet broadcasting.

Working principle

The TC74LCX373FT(EL) is composed of three Schottky Disable buffers. A Schottky Disable buffer is a device that provides a high impedance output state while the input signal is low, and a low impedance output state when the input is high. This is useful for avoiding loading the input and output signals. The power required by the buffer is very low in comparison with other logic families.

The TC74LCX373FT(EL) contains an asynchronous reset, latching enable, and data inputs that allow for data exchange from a low voltage TTL (LVTTL) logical level without needing to adjust the input and output voltages. The TC74LCX373FT(EL) is available in two logical levels that are compatible with most memory and logic families: 2.7V and 3.3V as well as 5V.

The TC74LCX373FT(EL) includes an enabled/disabled (also called active-low or active-high) logic input that controls the internal latch. Once the latch is enabled, any change occurring at the data inputs will be latched on the corresponding outputs. It requires a high-level signal to enable the outputs and propagate the data. When the enable input is set to a low-level state, all outputs will be disabled.

The asynchronous reset input provides a bypass to the RESET signal. The reset condition is defined by the logic state of the reset input. The initial setting of the outputs is determined by the logic state of the reset signal. The reset is a low-level-active control input and has the last data loaded into the latch ignored.

The TC74LCX373FT(EL) provides latched outputs with improved noise margins, eliminating the need for external buffering in many applications. Its low input and output signals allow for signaling up to 250MHz with a supply voltage as low as 2.7V and low power consumption. The TC74LCX373FT(EL) is an ideal choice for any application requiring high speed and reliable data transfer.
