74HC258D,653

Signal Switches, Multiplexers, Decoders Overview

The 74HC258D,653 is a high-speed Si-gate CMOS quad 2-input multiplexer with inverting 3-state outputs. It selects 4 bits of data from two sources controlled by a common select input (S). Outputs are forced to a high-impedance OFF-state when the output enable (OE) input is HIGH. The device complies with JEDEC standard no. 7A and operates within a supply voltage range of 2.0 V to 6.0 V. It features ESD protection exceeding 2000 V (HBM) and 200 V (MM), and is specified for ambient temperatures from −40 °C to +125 °C.
