74AC11257DWR Description

Short technical summary and product information.

The Texas Instruments 74AC11257DWR is a high-performance 4-bit, 4 x 2:1 multiplexer. This device is designed to interface signals from multiple 4-bit data sources to four output data lines within bus-organized systems. Its 3-state outputs ensure that the data lines are not loaded when the output-enable (OE) input is at a high logic level, providing flexibility in system design.

 

Featuring a flow-through architecture, the 74AC11257DWR optimizes PCB layout. The center-pin VCC and GND configurations are implemented to minimize high-speed switching noise. This multiplexer operates over a voltage range of 3V to 5.5V and maintains functionality across an industrial temperature range of -40°C to 85°C. It also offers typical latch-up immunity of 500mA at 125°C.

 

The device is available in a 20-SOIC surface mount package, measuring 0.295 inches (7.50mm) in width. Proper integration requires ensuring the output-enable (OE) is tied to VCC through a pull-up resistor for high-impedance state during power up or down, with the resistor value determined by the driver's current-sinking capability.
