74HC237N,652

Signal Switches, Multiplexers, Decoders Overview

The NXP USA Inc. 74HC237N,652 is a high-speed Si-gate CMOS device functioning as a 3-to-8 line decoder and demultiplexer with address latches at the three input pins (A0 to A2). It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The component utilizes a DIP16 plastic dual in-line package containing 16 leads. Propagation delay from address inputs to outputs reaches a maximum of 48 ns at 4.5 V, while latch enable transitions exhibit delays up to 57 ns under identical conditions.
