The document describes the TC74LCX157 series of high-performance CMOS multiplexers designed for use in 3.3 Volt systems while maintaining low power dissipation. The device consists of four 2-input digital multiplexers with common select and strobe inputs, featuring pin compatibility with standard 74 series logic.
| Propagation Delay Time | 6.0ns (Max.) at 3.0V-3.6V |
|---|---|
| Output Current | 24mA (Min.) at 3.0V |
| Latch-up Performance | +500mA |
| Operating Temperature | -40~85 °C |
Yes, the device features 5V tolerant inputs and outputs for interfacing to 5V supply environments.
When the STROBE input is held 'H' level, data selection is inhibited and all outputs become 'L' level.
