QUADRUPLE 2-LINE TO 1-LINE DATA SELECTORS/MULTIPLEXERS WITH 3-STATE OUTPUTS

These quadruple 2-line to 1-line data selectors/multiplexers are designed for 4.5-V to 5.5-V VCC operation. The AHCT257 devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable (OE) input is at the high Logic level. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The SN54AHCT257 is characterized for operation over the full military temperature range of 55C to 125C. The SN74AHCT257 is characterized for operation from 40C to 85C. By Texas Instruments
