74HC253D,653

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HC253D,653 is a dual 4-bit multiplexer housed in an SO16 (SOT109-1) plastic small outline package. It features two independent multiplexers with four binary inputs each, shared select inputs (S0, S1), and separate active-low output enable inputs (nOE). The device operates within a supply voltage range of 2.0 V to 6.0 V. Propagation delay from input to output ranges from 30 ns to 53 ns at 4.5 V to 6.0 V. It supports a wide operating temperature range from -40 °C to +125 °C.
