Nexperia USA Inc. 74HC154D,653

Overview

74HC154D,653 from Nexperia is a 4-to-16 line decoder/demultiplexer in SO24 package, decoding binary address inputs A0–A3 into 16 active-LOW outputs (Y0–Y15) with dual active-LOW enable inputs (E0, E1). It operates from 2.0 V to 6.0 V, delivers propagation delay as low as 10 ns at VCC = 6.0 V, and supports industrial temperature range (−40 °C to +125 °C). It serves in memory address decoding, I/O expansion, and logic-level demultiplexing in embedded control systems.

For engineers reviewing the 74HC154D,653 datasheet, 74HC154D,653 pinout, 74HC154D,653 application, or 74HC154D,653 equivalent, this device is selected for precise 1-of-16 output selection with CMOS-level input compatibility, low static current (<160 μA), and robust noise immunity-critical for reliable address routing in microcontroller peripheral interfaces and programmable logic subsystems.

Technical Context

The 74HC154D implements combinational logic decoding using standard CMOS architecture, where all 16 outputs are mutually exclusive and active LOW. Its two enable inputs (E0, E1) require both to be LOW for normal decoding; either HIGH forces all outputs HIGH-enabling hierarchical cascading or global output disable.

Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The device complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), and meets HBM ESD >2000 V and CDM >1000 V per JS-001/JS-002.

FAQ

Can 74HC154D,653 operate at 3.3 V supply?

Yes. The 74HC154D,653 is fully specified from 2.0 V to 6.0 V, including 3.3 V operation. At VCC = 3.3 V, VIH is guaranteed ≥2.31 V and VIL ≤1.0 V per datasheet Table 6, ensuring reliable interface with 3.3 V microcontrollers without level shifting.

What happens when both E0 and E1 are HIGH?

When either E0 or E1 is HIGH, all 16 outputs (Y0–Y15) are forced HIGH regardless of address inputs. This is a defined disable state per Table 3 - not high-impedance - making it suitable for wired-OR bus architectures or global output blanking.

Is there a version with 3-state outputs?

No. The 74HC154D,653 has push-pull active-LOW outputs only. For 3-state capability, consider the 74HC251 (8-to-1 multiplexer with 3-state) or discrete buffer solutions - the 74HC154 family does not include tri-state variants.

How is thermal performance affected in SO24 package?

The SO24 (SOT137-1) package has total power dissipation rated at 500 mW at Tamb ≤119 °C, derating linearly by 16.2 mW/K above that. At full 125 °C ambient, maximum usable power drops to ~400 mW - sufficient for typical decode/demux loads drawing <10 mA per output.
