Nexperia USA Inc. 74HC139PW-Q100J

Overview

74HC139PW-Q100 from Nexperia is an automotive-qualified dual 2-to-4 line decoder/demultiplexer in TSSOP16 package, operating from -40 °C to +125 °C with CMOS-level inputs, active-LOW outputs, and independent enable-controlled decoding paths. It supports memory address decoding and data routing in engine control units and body electronics.

For engineers reviewing the 74HC139PW-Q100 datasheet, 74HC139PW-Q100 pinout, 74HC139PW-Q100 application, or 74HC139PW-Q100 equivalent, key selection criteria include propagation delay (14 ns typ @ 4.5 V), AEC-Q100 Grade 1 qualification, dual-decoder independence, active-LOW output logic, and TSSOP16 thermal derating profile (8.5 mW/K above 91 °C).

Technical Context

This device integrates two functionally identical, electrically isolated 2-to-4 decoders-each accepting binary address inputs (A0, A1) and an active-LOW enable (nE)-to drive four mutually exclusive active-LOW outputs (nY0–nY3). Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

It operates under JEDEC Standard No. 7A compliance and supports both memory decoding and 1-to-4 demultiplexing via nE as data input. Static characteristics confirm VIH = 3.15 V min (VCC = 4.5 V), VOL = 0.26 V max (IO = 4 mA), and ICC = 160 μA max over full temperature range.

FAQ

Can 74HC139PW-Q100 operate at 3.3 V supply?

Yes. The 74HC139PW-Q100 is fully specified down to VCC = 2.0 V, with guaranteed VIH = 1.5 V min and VOL = 0.26 V max at 4 mA load when VCC = 3.3 V. Its CMOS inputs provide adequate noise margin in 3.3 V systems, and propagation delay remains within 22 ns (max) across -40 °C to +125 °C.

What is the maximum output sink current per Y pin?

Each output (nY0–nY3) is rated for ±4.0 mA DC output current at VCC = 4.5 V, with VOL ≤ 0.26 V. At VCC = 6.0 V, it supports ±5.2 mA with VOL ≤ 0.26 V. Exceeding these values risks violating VOL spec or triggering internal current limiting, especially at high temperature.

How does the enable input function in demultiplexer mode?

When used as a 1-to-4 demultiplexer, one decoder's nE pin serves as the data input, while its A0/A1 pins select the output channel. For example, applying data to 1E and address bits to 1A0/1A1 routes the signal to exactly one of 1Y0–1Y3-leveraging the inherent active-LOW decode logic without external inversion.

Is thermal derating required for continuous operation at 125 °C?

Yes. For the TSSOP16 (SOT403-1) package, total power dissipation derates linearly at 8.5 mW/K above +91 °C. At +125 °C, Ptot must be limited to 500 mW − (8.5 mW/K × 34 K) = 211 mW. This requires careful layout with thermal vias and copper pour to maintain junction temperature within limits.
