Product details

Dual 2:4 decoder for address and control routing

The SN74AHC139PWR integrates two independent 1-of-4 decoder/demultiplexer circuits in a single 16-TSSOP package.

Supply flexibility and signal integrity

A single supply rail powers both decode circuits, simplifying the power distribution network. The wide 2V-5.5V range means the same BOM line can serve a 5V-tolerant legacy bus and a 3.3V FPGA bank — the decoder's propagation delay shifts with Vcc, so timing closure should be verified at the lowest operating voltage. The 0.173-inch body height keeps it within standard pick-and-place clearance limits.
