STMicroelectronics M74HC257RM13TR - Quad 2-Channel Multiplexer with 3-State Outputs

The M74HC257RM13TR from STMicroelectronics is a high-speed CMOS quad 2-channel multiplexer with 3-state outputs that is designed to meet the requirements of both high-speed and low-power consumption in modern electronic systems. This integrated circuit is part of the HC family which operates with a power supply range of 2V to 6V, making it compatible with TTL levels and ideal for interfacing with microprocessors.

Enclosed in a compact SOP-16 (Small Outline Package) with 16 pins, the M74HC257RM13TR offers four multiplexers with two inputs each (A and B), along with an output enable (OE) and a common data select input (S). When the output enable (OE) is high, the outputs are in a high impedance state, allowing for the connection of multiple outputs to a common bus without the risk of conflict.

The device's true data paths make it suitable for multiplexing and demultiplexing applications, as well as for data routing purposes. The low quiescent current and high noise immunity of the CMOS process ensure that the M74HC257RM13TR is reliable for use in a wide range of industrial and consumer applications, including computers, communication equipment, and control systems.

Key features of the M74HC257RM13TR include:

• High-speed operation: tPD = 15 ns (typ) at VCC = 6V
• Low power dissipation: ICC = 4 µA (max) at TA = 25°C
• Wide operating voltage range: VCC (opr) = 2V to 6V
• Pin and function compatible with 74 series 257
• ESD performance: HBM > 1 KV; MM > 200V
• Available in SOP-16 package for reduced space requirements

The STMicroelectronics M74HC257RM13TR is a versatile multiplexer that offers reliable performance with the added benefit of 3-state outputs, making it a suitable choice for designers looking to optimize their high-speed digital circuit designs with an efficient and flexible switching component.
