The 74ACT157 is a high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER with preliminary data from May 1997.
It has a high-speed operation with a propagation delay of 5.5ns at VCC=5V and low power dissipation with a maximum ICC of 8µA at TA=25oC.
The device is compatible with TTL outputs and has a 50Ω transmission line driving capability.
It is designed for low power applications and is ideal for interfacing directly with High Speed CMOS systems, TTL, NMOS, and CMOS output voltage levels.
The device consists of four 2-input digital multiplexers with common select and strobe inputs and is non-inverting.
It has improved latch-up immunity and is equipped with protection circuits against static discharge, giving it 2KV ESD immunity and transient excess voltage.
The device operates within an operating voltage range of VCC(OPR)=4.5V to 5.5V and has an improved latch-up immunity.
The recommended operating conditions, absolute maximum ratings, pin description, and IEC logic symbols are also provided.
Additionally, the device's DC specifications, test circuit and electrical characteristics, and mechanical data are included in the preliminary data.
