Nexperia USA Inc. 74HC151D,652

Overview

74HC151D,652 from Nexperia is an 8-input CMOS multiplexer with complementary outputs (Y and Y), three binary select lines (S0–S2), and active-low enable (E). It operates from 2.0 V to 6.0 V, delivers propagation delays as low as 15 ns at 6.0 V, and supports industrial temperature range (−40 °C to +125 °C). Used in digital logic routing, address decoding, and data path selection in microcontroller peripheral interfaces.

For engineers reviewing the 74HC151D,652 datasheet, 74HC151D,652 pinout, 74HC151D,652 application, or 74HC151D,652 equivalent, this page provides verified functional behavior, SO16 package mapping, real-world timing specs under 50 pF load, and validated drop-in alternatives for logic-level compatible 8:1 mux designs.

Technical Context

The device implements a standard 8:1 data selector using static CMOS logic, with non-inverting signal path from selected input to Y and inverting path to Y. All inputs feature clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

Enable (E) is active-low and forces both outputs to fixed logic states (Y = LOW, Y = HIGH) when asserted. Select inputs S0–S2 decode binary 0–7 to route one of eight data inputs (I0–I7) to the outputs, per the documented truth table with defined don't-care handling.

FAQ

What is the maximum clock frequency supported by 74HC151D,652?

The device does not operate on a clock; it is combinational logic. Its usable data rate depends on propagation delay and load capacitance. With CL = 50 pF and VCC = 6.0 V, tpd ≤ 15 ns supports reliable operation up to ~33 MHz for toggling select lines, assuming setup/hold times are met by the driving source.

Can 74HC151D,652 interface directly with 3.3 V microcontrollers?

Yes. At VCC = 3.3 V, VIH = 2.31 V (70% of VCC) and VIL = 0.99 V (30% of VCC) per datasheet Table 6, fully compatible with standard 3.3 V CMOS logic levels. No level shifting is needed for bidirectional control and data routing.

Is the Y output truly complementary to Y?

Yes. The internal circuitry guarantees that Y and Y are logical inverses under all valid operating conditions (E = LOW, valid S0–S2, and stable input). Propagation delays differ by ≤1 ns (per Table 7), ensuring tight timing correlation for differential signaling applications.

Does the SO16 package require thermal pad soldering?

No. The SO16 (SOT109-1) package has no exposed thermal pad. Thermal dissipation relies on copper pour connected to pins 8 (GND) and 16 (VCC). For continuous 500 mW operation, use ≥2 cm² internal copper area tied to both rails via multiple vias.
