Nexperia USA Inc. 74HC158D,653

Overview

74HC158D,653 from Nexperia is a quad 2-input inverting multiplexer in SO16 package, operating from −40 °C to +125 °C with V_CC = 2.0–6.0 V, 4-bit data selection via common select (S), active-low enable (E), and inverted outputs (1Y–4Y). It implements logic-equivalent 4-pole/2-position switching for register-to-bus routing and irregular 2-variable function generation.

For engineers reviewing the 74HC158D,653 datasheet, 74HC158D,653 pinout, 74HC158D,653 application, or 74HC158D,653 equivalent, key selection criteria include guaranteed propagation delay ≤25 ns at V_CC = 4.5 V, ESD protection >2000 V HBM, JEDEC 7A compliance, and inverting output behavior distinguishing it from 74HC157.

Technical Context

The device integrates four independent 2:1 multiplexers sharing one select input (S) and one active-low enable (E), each producing logically inverted outputs. All outputs go HIGH when E is HIGH, regardless of S or data inputs - enabling global output disable without bus contention.

Its CMOS architecture delivers rail-to-rail output swing, low static current (≤160 μA at T_A = −40 °C to +125 °C), and defined input thresholds (V_IL ≤ 1.35 V, V_IH ≥ 3.15 V at V_CC = 4.5 V), supporting direct interfacing with LSTTL and other HC-series logic.

FAQ

What is the maximum clock frequency supported by the 74HC158D,653?

The 74HC158D,653 does not operate on a clock; it is combinational logic. Its maximum usable data rate is determined by propagation delay: at V_CC = 4.5 V and C_L = 50 pF, t_pd ≤ 25 ns, supporting reliable switching up to ~20 MHz for clean edge-triggered sampling. For higher rates, reduce load capacitance or use lower V_CC.

Can the 74HC158D,653 interface directly with 3.3 V microcontrollers?

Yes. At V_CC = 3.3 V, VIH is guaranteed ≥2.31 V and VIL ≤ 1.0 V per interpolation of datasheet specs, exceeding standard 3.3 V CMOS thresholds (VIH = 2.0 V, VIL = 0.8 V). Outputs swing rail-to-rail, ensuring compatible logic levels with 3.3 V GPIOs without level shifters.

Why does the 74HC158D,653 force outputs HIGH when E is HIGH?

This active-low enable design ensures fail-safe bus isolation: when the enable signal is deasserted (HIGH), all outputs enter a known HIGH state, preventing floating nodes or unintended activation of downstream devices like latches or drivers. It simplifies system reset sequencing and avoids metastability during power-up.

How does the 74HC158D,653 differ from the 74HC153 in practical use?

The 74HC153 is a dual 4:1 multiplexer (two independent 4-input selectors), whereas the 74HC158 is a quad 2:1 multiplexer (four independent 2-input selectors sharing one select line). The 74HC158 suits applications needing simultaneous 2-source selection across 4 data lines (e.g., register banks); the 74HC153 fits cases requiring independent 4-source selection per channel (e.g., ADC input routing).
