SN74F257N

Overview

The SN74F257N is a quad 2-to-1 data selector/multiplexer with three-state outputs from the Texas Instruments SN74F series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 6 ns. The device contains four independent circuits, each selecting between two inputs based on a control signal. It is housed in a 16-pin PDIP package designed for through-hole mounting. The component supports an operating temperature range from 0°C to +70°C.
