What are the key features of CD74HC237PWR?
- 3-to-8 line decoding with integrated address latches, eliminating external latch ICs for address demultiplexing
- High-speed CMOS HC family for wide supply range operation from 2 V to 6 V
- 8 active-low outputs with 5.2 mA IOL drive suitable for LED and logic-level loads
- Latched inputs allow transparent or clocked address capture for multiplexed bus systems
- 16-pin SOIC package (JESD-30 R-PDSO-G16) with 50 pF load capacitance for reliable high-frequency switching
What is CD74HC237PWR used for?
The CD74HC237PWR is widely used in microprocessor address bus decoding to select one of 8 memory or I/O blocks from a 3-bit address, with the integrated latch holding the selected address stable during the data transfer phase. It also serves as a demultiplexer in display driver circuits, relay driver arrays, and industrial I/O expansion boards where a compact 16-pin SOIC footprint is required. The wide 2 V to 6 V supply range makes it compatible with both 3.3 V microcontrollers and 5 V legacy systems.

Frequently Asked Questions
How does the integrated address latch in the CD74HC237PWR reduce external component count in a bus decoding circuit?
The CD74HC237PWR includes a transparent latch on the 3 address inputs (A0–A2), which captures and holds the address when the latch enable goes low. This eliminates the need for a separate 74HC373 or similar octal latch, saving one IC and associated decoupling capacitors while driving any of 8 output lines from a 50 pF-loaded bus at up to 5.2 mA.
What supply voltage range does the CD74HC237PWR support, and which mixed-voltage systems can it serve?
The CD74HC237PWR operates from 2 V to 6 V, covering 3.3 V microcontroller systems, 5 V TTL-compatible designs, and battery-powered devices down to 2 V. This range lets it decode addresses in both modern ARM-based boards and legacy 5 V 8051 or Z80 systems without voltage-level translation, simplifying mixed-voltage board integration.
In a memory-mapped I/O design, how many addressable devices can the CD74HC237PWR select using its 3-bit input?
With 3 address inputs (A0, A1, A2), the CD74HC237PWR can uniquely select 1 of 8 output lines, corresponding to 8 independently addressable devices or memory blocks. Each output drives loads with up to 5.2 mA IOL and 50 pF capacitance, sufficient to enable chip-select inputs on SRAM, EEPROM, or peripheral ICs in microprocessor systems clocked up to tens of megahertz.
When should a designer choose CD74HC237PWR over a plain CD74HC138 decoder without latches?
CD74HC237PWR is the right choice when address lines are only valid for a short window during a bus cycle and must be latched before the decoder outputs can be relied upon downstream. The internal latch allows the host microcontroller to multiplex address and data on the same 8-bit bus, a common technique in 8051 and AVR designs, eliminating an external 74HC373 and saving at least one 16-pin SOIC package worth of board area.
