SNJ54LS258BFK TI Multiplexer | 4x2:1 | Military Temp, -55 to +125°C

Product Overview

The SNJ54LS258BFK is a high-performance quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments, designed for military and aerospace applications. It features Schottky-clamped TTL technology for high speed and low power consumption. The device selects one of two 4-bit data sources under control of a common Select input (S). The outputs are three-state, allowing for bus-organized systems. The SNJ54LS258BFK is specified for operation over the full military temperature range of -55°C to +125°C and is available in a ceramic flat package (FK).
