Nexperia USA Inc. 74HC153DB,118

Overview

74HC153DB,118 from Nexperia is a dual 4-input CMOS multiplexer with independent active-low enable inputs (1E, 2E), common binary select lines (S0, S1), and non-inverting outputs (1Y, 2Y). It operates from 2.0 V to 6.0 V, delivers propagation delays as low as 14 ns at VCC = 6.0 V, and supports industrial temperature range (−40 °C to +125 °C). It routes one of four data inputs per channel to its output under select control - used in digital logic routing, address decoding, and bus arbitration circuits.

For engineers reviewing the 74HC153DB,118 datasheet, 74HC153DB,118 pinout, 74HC153DB,118 application, or 74HC153DB,118 equivalent, key selection criteria include supply voltage compatibility (2.0–6.0 V), enable-controlled channel isolation, propagation delay vs. VCC/load, input level tolerance (CMOS), and SO16 package thermal and layout constraints.

Technical Context

The device implements two independent 4:1 multiplexers sharing S0/S1 select lines but featuring separate enables (1E, 2E), enabling selective activation of either channel without affecting the other. Each multiplexer selects one of four inputs (e.g., 1I0–1I3) based on the 2-bit binary code on S0/S1 and drives it to the corresponding output (1Y or 2Y) when its enable is LOW.

Input clamping diodes allow safe interfacing to voltages exceeding VCC when current-limiting resistors are used. The logic is fully static CMOS, with guaranteed noise immunity, latch-up immunity >100 mA (JESD78 Class II B), and ESD robustness (HBM >2000 V, CDM >1000 V).

FAQ

What is the maximum clock/data rate supported by 74HC153DB,118?

The device has no internal clock; its usable data rate depends on propagation delay and system setup/hold timing. With tPD = 14 ns (VCC = 6.0 V), it supports reliable operation up to ~25 MHz in combinational routing paths when paired with appropriate PCB layout and load capacitance ≤50 pF.

Can 74HC153DB,118 operate at 3.3 V supply?

Yes - the 74HC153DB,118 is fully specified from 2.0 V to 6.0 V. At VCC = 3.3 V, VIH = 2.31 V (70% of VCC), VIL = 0.99 V (30%), and typical tPD is ~22 ns (CL = 50 pF), making it compatible with 3.3 V microcontrollers and FPGAs.

Is there a pin-compatible 74HC153 variant in TSSOP16?

Yes - the 74HC153PW,118 uses the same pinout in TSSOP16 (SOT403-1) package. It shares identical logic, timing, and DC specs but has different thermal characteristics (θJA = 117 K/W) and smaller footprint (4.4 mm width).

Does 74HC153DB,118 require external pull-up resistors on enable or select lines?

No - all inputs are CMOS with high-impedance, rail-to-rail compatible thresholds. Pull-ups are unnecessary unless floating-state prevention is required in your system architecture; unused inputs should be tied to VCC or GND to prevent oscillation and excess current draw.
