Key Features:
Logic Series:HC series,compatible with CMOS logic levels.
Input/Output Configuration:3 input lines and 8 output lines,supporting operating voltages up to 5V.
Propagation Delay:Typical value of 50 ns,ensuring high-speed data transmission and decoding.
Operating Temperature Range:From-40°C to+125°C,suitable for a wide range of industrial environments and applications.
Current Capability:High and low-level output currents of 5.2 mA,meeting standard drive requirements.
Package:SO-16 package,compact in size,ideal for space-constrained designs.
Functions and Benefits:
Multiple Enable Inputs:The 74HC138D,653 provides three enable inputs(E1,E2,and E3),where each output is high when E1 and E2 are low and E3 is high.This feature allows the device to be easily expanded to a 1-to-32 line decoder using only four 74HC138 ICs and one inverter.
Decoding and Demultiplexing:The device can function as a decoder for three binary-weighted address inputs or as a demultiplexer with 8 outputs.
Parallel Expansion Capability:Thanks to the multi-input enable function,designers can easily expand the circuit for larger decoding tasks.
ESD Protection:Provides electrostatic discharge(HBM)protection of over 2000V,ensuring reliability in harsh environments.
Mutually Exclusive Outputs:The 8 outputs are independent,ensuring that only one output is low at a time for different input combinations,facilitating memory chip selection decoding.
Applications:
Serial-to-parallel data conversion
Memory chip selection decoding
Remote control latch register
Data bus separation and selection
