Nexperia USA Inc. 74HC153DB,112

Overview

74HC153DB,112 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 address/data routing, signal selection, and digital logic reconstruction.

For engineers reviewing the 74HC153DB,112 datasheet, 74HC153DB,112 pinout, 74HC153DB,112 application, or 74HC153DB,112 equivalent, this device serves as a standard dual-channel data selector in combinational logic design, bus management, and test instrumentation where TTL-compatible input thresholds are not required and low-power CMOS operation is critical.

Technical Context

The 74HC153DB,112 implements two independent 4:1 multiplexers sharing S0/S1 select lines but featuring separate enables (1E, 2E), enabling synchronized or asynchronous channel activation. Each multiplexer selects one of four inputs (e.g., 1I0–1I3) based on the 2-bit binary code at S0/S1, with output forced LOW when its enable is HIGH.

Its CMOS architecture ensures high noise immunity (typical VIH = 4.2 V at VCC = 6.0 V), low static current (ICC ≤ 8.0 μA at 25 °C), and robust ESD protection (HBM > 2000 V). Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

FAQ

What is the maximum clock frequency supported by the 74HC153DB,112 for reliable data selection?

The 74HC153DB,112 does not operate on a clock; it is a combinational logic device. Its maximum usable data rate is determined by propagation delay: at VCC = 6.0 V and CL = 50 pF, tpd ≤ 26 ns (−40 °C to +125 °C), supporting reliable switching up to ~35 MHz in synchronous systems with appropriate setup/hold margins.

Can the 74HC153DB,112 be used with 3.3 V microcontrollers without level shifting?

Yes. With VCC = 3.3 V, the 74HC153DB,112 exhibits VIH ≈ 2.3 V and VIL ≈ 1.1 V (per static characteristics), fully compatible with standard 3.3 V CMOS outputs. Its 2.0–6.0 V supply range eliminates need for external level translators in mixed-voltage digital systems.

Is the 74HC153DB,112 pin-compatible with the 74HC153D (SO16) variant?

No. The 74HC153DB,112 uses SSOP16 (SOT338-1) packaging with 0.65 mm pitch, while the 74HC153D uses SO16 (SOT109-1) with 1.27 mm pitch. Pin functions are identical, but physical layout, land pattern, and soldering requirements differ-PCB redesign is required for substitution.

Does the 74HC153DB,112 support hot-swap or live-insertion applications?

It supports limited hot-swap behavior due to input clamp diodes and JESD78 latch-up immunity (>100 mA), but lacks dedicated hot-swap protection circuitry. For robust live insertion, external current limiting and sequencing controls are recommended-especially during VCC ramp-up before logic signals stabilize.
