Nexperia USA Inc. 74HC4514PW-Q100J

Overview

74HC4514PW-Q100 from Nexperia is an automotive-qualified 4-to-16 line decoder/demultiplexer with input latches, featuring four binary address inputs (A0–A3), latch enable (LE), active-low enable (E), and 16 active-high outputs (Q0–Q15). It operates from 2.0 V to 6.0 V, supports −40 °C to +125 °C ambient range, and delivers propagation delays as low as 12 ns at VCC = 6.0 V. Used in automotive body control modules for discrete output selection.

For engineers reviewing the 74HC4514PW-Q100 datasheet, 74HC4514PW-Q100 pinout, 74HC4514PW-Q100 application, or 74HC4514PW-Q100 equivalent, key selection criteria include latch-controlled output stability, AEC-Q100 Grade 1 qualification, TSSOP24 package thermal performance, and compatibility with 3.3 V/5 V logic systems.

Technical Context

This device integrates four independent D-type latches followed by a 4-to-16 binary decoder. Latch enable (LE) controls data capture timing: when LE is HIGH, outputs track A0–A3; when LE transitions LOW, the current address is latched and held regardless of subsequent address changes. The enable input E operates independently-when LOW, the latched address selects one HIGH output; when HIGH, all outputs force LOW.

Input clamping diodes allow safe interfacing to voltages exceeding VCC using external current-limiting resistors. Static and dynamic characteristics are fully specified across −40 °C to +125 °C, with VIH/VIL thresholds scaling with VCC (e.g., VIH = 3.15 V min at VCC = 4.5 V), and propagation delay tightly bounded (tpd ≤ 45 ns max over full temperature range at VCC = 6.0 V).

FAQ

What is the function of the LE (latch enable) pin?

The LE pin controls data capture timing: when LE is HIGH, outputs follow A0–A3 in real time; on the falling edge of LE, the current 4-bit address is stored in internal latches and held indefinitely-even if A0–A3 change afterward. This ensures output stability during address bus contention or microcontroller interrupt latency, critical for driving relays or solenoids without unintended activation.

Can 74HC4514PW-Q100 operate at 3.3 V supply?

Yes. The device is fully specified from 2.0 V to 6.0 V, with guaranteed VIH = 2.1 V min and VIL = 1.35 V max at VCC = 4.5 V, and scaled thresholds at 3.3 V (VIH ≈ 2.0 V, VIL ≈ 1.1 V). All timing and drive parameters-including tpd ≤ 22 ns (typ) and ±4 mA output-remain valid at 3.3 V, enabling direct interface with 3.3 V microcontrollers without level translation.

How does the E (enable) input interact with latched data?

The E input is independent of the latch: it gates the decoder output but does not affect latch contents. When E = LOW, the latched address selects exactly one HIGH output (Qn); when E = HIGH, all 16 outputs force LOW regardless of latch state. This allows synchronous blanking of all outputs-e.g., during system reset or fault condition-without disturbing the stored address.

Is this device suitable for driving LEDs directly?

Yes, within limits. Each Qn output can sink or source up to ±4.0 mA at VCC = 4.5 V (±5.2 mA at VCC = 6.0 V), sufficient for low-current indicator LEDs (e.g., 2 mA @ 2.0 V forward voltage with 1 kΩ series resistor). For higher-current loads like incandescent bulbs or relays, external drivers are required-but the latch ensures stable LED state during microcontroller sleep or bus arbitration.
