Renesas 74HC139P-E

Overview

74HC139P-E from Renesas is a dual 2-to-4-line decoder/demultiplexer in a 16-pin DIP package, operating from 2 V to 6 V with 14 ns typical propagation delay (CL = 50 pF), ±25 mA output drive, and 4 µA max quiescent supply current. It implements two independent decoders each with active-low enable (1G/2G) and binary-select inputs (A/B), driving four active-low outputs per section in digital address decoding and signal routing applications.

For engineers reviewing the 74HC139P-E datasheet, 74HC139P-E pinout, 74HC139P-E application, or 74HC139P-E equivalent, key selection criteria include its dual-decoder architecture, wide VCC range, low-power CMOS compatibility, and discrete enable control per section-critical for memory address selection, I/O port expansion, and logic-level multiplexing in industrial control and embedded systems.

Technical Context

The 74HC139P-E integrates two identical 2-to-4-line decoder blocks sharing no internal resources-each has dedicated G, A, B inputs and Y0–Y3 outputs. Each decoder operates asynchronously with independent active-low enable gating, allowing selective activation of one decoder while the other remains high-impedance inactive.

Logic behavior follows standard binary decoding: when G = L, outputs Y0–Y3 reflect the inverse of the 2-bit input combination (A,B); all outputs remain high when G = H. Input thresholds are compatible with both HC and TTL logic families across the full 2–6 V supply range.

FAQ

What is the logic function implemented by the 74HC139P-E?

The 74HC139P-E implements two independent 2-to-4-line decoders, each with an active-low enable input (1G or 2G) and two binary select inputs (A and B). When the enable is low, exactly one of the four active-low outputs (Y0–Y3) goes low based on the (A,B) combination; all outputs remain high when enable is high. This behavior is defined in the function table on page 2 of the HD74HC139 datasheet.

Does the 74HC139P-E support 3.3 V operation?

Yes, the 74HC139P-E supports 3.3 V operation fully-its specified VCC range is 2 V to 6 V, and all electrical characteristics including VIH/VIL thresholds, propagation delay, and output drive are guaranteed across this range. At 3.3 V, VIH is 2.31 V min and VIL is 0.99 V max, providing solid noise margins for 3.3 V CMOS systems.

What is the maximum output sink current for the 74HC139P-E?

The 74HC139P-E guarantees ±25 mA maximum output current per pin under absolute maximum ratings, and its DC electrical characteristics specify VOL ≤ 0.33 V at IOL = 4 mA (VCC = 4.5 V) and ≤ 0.33 V at IOL = 5.2 mA (VCC = 6.0 V). This confirms robust sink capability for driving LEDs, small relays, or LSTTL loads without external buffers.

Is the 74HC139P-E pin-compatible with other 74HC139 variants?

Yes-the 74HC139P-E shares identical pinout and logic function with all HD74HC139 variants (e.g., HD74HC139FPEL, HD74HC139RPEL), differing only in package type (DIP vs. SOP vs. TSSOP). The P-suffix denotes the 16-pin DIP package (PRDP0016AE-B), and pin numbering-including GND at pin 8 and VCC at pin 16-is consistent across all versions.

What is the quiescent supply current of the 74HC139P-E at 5 V?

The 74HC139P-E draws a maximum quiescent supply current (ICC) of 4 µA at VCC = 6.0 V and Ta = 25°C, and up to 40 µA over the full operating temperature range (–40°C to +85°C). At 5 V, ICC remains well within the 4 µA typical spec-confirmed by the "Quiescent supply current" row in the Electrical Characteristics table on page 3 of the datasheet.
