Product Description

The SN74HCT257N is a 2-to-1 quadruple Data Selector/Multiplexer with 3-state outputs. It is 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 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 pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver.
Typical tpd = 17ns
Inputs are TTL-voltage compatible
Provide bus interface from multiple sources in high-performance systems
Buffered inputs and outputs
80µA Maximum low power consumption
±6mA Output drive at 5V
1µA Maximum low input current
