What are the key features of CD74HC137PW?
- 3-line to 8-line inverting decoder with on-chip address latches for glitch-free output switching in bus-oriented systems
- Wide 2 V to 6 V supply range compatible with 3.3 V and 5 V logic families without level-shifting
- Three independent enable inputs allow cascading multiple CD74HC137PW devices to expand from 8 to 64 or more decoded outputs
What is CD74HC137PW used for?
The CD74HC137PW is used in address decoding for microcontroller and FPGA memory maps, enabling selection among up to 8 peripheral chips from 3 address lines. It is also applied in data routing and demultiplexing for industrial control panels, where latched address inputs hold the selected output stable during bus transitions. The TSSOP-16 package and 2 V to 6 V operating range make it a compact choice for embedded systems and communication equipment requiring simple address-based chip-select generation.

Frequently Asked Questions
What supply voltage range does the CD74HC137PW support, and is it compatible with 3.3 V systems?
The CD74HC137PW operates from 2 V to 6 V, making it fully compatible with both 3.3 V and 5 V logic systems without external level translators. At 3.3 V it meets standard HC-family input thresholds, allowing direct connection to FPGA and microcontroller GPIO running at 3.3 V rails.
How does the address latch feature of CD74HC137PW prevent output glitches in address-decode circuits?
The on-chip address latches capture the 3-bit address when the latch enable input is asserted, holding the selected output stable even if address lines change afterward. This prevents false triggering of peripheral chips during bus turnaround cycles and is especially important in 8-bit microprocessor systems with multiplexed address and data buses.
How many outputs can be expanded by cascading multiple CD74HC137PW decoders with its 3 enable inputs?
Each CD74HC137PW decodes 3 address inputs to 8 outputs, and using the 3 enable inputs to cascade devices scales the decoded outputs to 16, 32, or 64 lines. For example, 2 devices with one higher-order enable bit select between them provides 16 unique decoded outputs from 4 address lines.
For a compact PCB design, what board space does the 16-pin TSSOP package of CD74HC137PW require?
The TSSOP-16 package has a 5 mm body length, 4.4 mm width, and 0.65 mm pin pitch, occupying roughly 22 mm² of PCB area. This is significantly smaller than a standard SOIC-16 footprint, making CD74HC137PW a good choice when routing address decode logic in space-constrained board layouts alongside dense connector banks.
