SN74AHCT157PWR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT157PWR is a quad 2-line to 1-line data selector/multiplexer from Texas Instruments, belonging to the AHC logic family. It features four independent multiplexers with a common output enable input and shared select lines. The device operates within a supply voltage range of 2 V to 5.5 V and utilizes a 16-pin TSSOP package. Key electrical parameters include a maximum propagation delay of 9.5 ns at 5 V and an operating temperature range from -40°C to +85°C. It provides latch-up performance exceeding 250 mA per JESD 78 standards.
