The SN74LVC245ANG4 is a monolithic transceiver, which functions as a logic-level translator with ready-to-use 3.3V operation. It acts as a bidirectional buffer/driver/receiver and can be used in both 2.5V and Vcc-L operation. The SN74LVC245ANG4 is just one of a broad range of devices included in Texas Instruments’ wide range of logic-level buffering, drivers, receivers, and transceivers.

The SN74LVC245ANG4 comprises of two 8-bit non-inverting buffers, with each buffer having a separate output enable (OE) pin. The two buffers are enabled according to the logic specified in the input G of the device. The two buffers can be either enabled (so that data passed through) or disabled (so that data is held in the input register). The two buffers can function as either two individual data buffers or as two portions of one 16-bit wide buffering/ driver register.

The device is characterized for operation from -40°C to 85°C and is operational across multiple voltages ranging from 2.7V up to 5.5V. The SN74LVC245ANG4 has outputs that can sink 24mA and source 2mA. The outputs have symmetrical dynamic characteristics, resulting in the device being stable regardless of the switching speed.

Input data (D1 - D8) is routed straight through the SN74LVC245ANG4 to the 3.3V LVTTL outputs (Q1 - Q8). When the G (enable) pin is HIGH, the chip is enabled and the data is transferred. When the enable pin is LOW, the chip is disabled and the data held in the output register. The two outputs can be operated independently of each other and can be separately enabled or disabled using the two output enable inputs (OE1, OE2).

The SN74LVC245ANG4 also has three dedicated outputs for signal control: Transmit Enable (T), Receive Enable (R), and Output Enable (OE). The T output is high impedance when disabled and driven low when enabled. The R signal is high impedance when enabled, and driven low when disabled. The OE signal is driven low when enabled, and high when disabled.

The logic family of the SN74LVC245ANG4 is LVCMOS. The device uses an LDHC (low-discharge high-capacitance) process, ensuring low output leakage current and high-switching capability. The on-resistance (RDS) of the device is low, which ensures high performance and stability of the device. The device also has a high-switching frequency, resulting in excellent noise rejection. All these features make the SN74LVC245ANG4 an ideal solution for a wide range of applications.

The SN74LVC245ANG4 is an ideal solution for a variety of applications, such as head-marker boards, interface signals between MCU and display panel, communication interface between two planes on a CPU board, and power-supply linking. Furthermore, the device is also suitable for consumer electronics, embedded applications, and battery-operated systems. It is also suitable for Automotive-grade applications, such as in-vehicle controller networks.

In conclusion, the SN74LVC245ANG4 is a monolithic 3.3-V transceiver, which provides high-speed logic-level translation, low power consumption, and low-discharge high-capacitance process. It is suitable for multiple applications such as head-marker boards, consumer electronics, embedded systems, and automotive-grade applications. The device is characterized for operation from -40°C to 85°C and provides excellent performance in ambient temperatures. The SN74LVC245ANG4 transceiver is reliable, robust, and ideal for a wide range of applications.
