Nexperia USA Inc. 74HC11D,652

Overview

74HC11D,652 from Nexperia is a triple 3-input AND gate logic IC in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, with propagation delay of 10–30 ns (VCC = 4.5–6.0 V), output drive capability of ±4.0 mA, and guaranteed operation from −40 °C to +125 °C. It serves as a combinational logic building block in digital control, address decoding, and enable gating circuits.

For engineers reviewing the 74HC11D,652 datasheet, 74HC11D,652 pinout, 74HC11D,652 application, or 74HC11D,652 equivalent, this page delivers verified functional identity, validated SO14 pin mapping, confirmed static/dynamic electrical specs, thermal and ESD ratings, and real-world substitution guidance - all grounded in Nexperia's Rev. 9 (2024) product data sheet.

Technical Context

This device implements three independent 3-input AND functions using CMOS technology, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Each gate exhibits symmetrical HIGH/LOW output voltage thresholds defined by VCC-dependent VIH/VIL levels.

It supports dual logic families: 74HC11D uses CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V), while its 74HCT11D variant accepts TTL-compatible inputs (VIH ≥ 2.0 V). Static current consumption is ≤40 μA over full temperature range, and dynamic power is governed by CPD = 18 pF.

Key Specifications

Pinout & Package

FAQ

Is 74HC11D,652 compatible with 3.3 V microcontroller GPIOs?

Yes. With VCC = 3.3 V, the 74HC11D,652 meets VIH ≥ 2.1 V and VIL ≤ 1.35 V per datasheet Table 6, ensuring reliable recognition of standard 3.3 V CMOS logic levels. Its output VOH ≥ 2.97 V and VOL ≤ 0.26 V at IO = ±4.0 mA also cleanly drive downstream 3.3 V inputs without level shifting.

Can 74HC11D,652 safely interface to 5 V signals while powered from 3.3 V?

Yes - but only with external current-limiting resistors. The integrated input clamp diodes allow VI up to VCC + 0.5 V (i.e., 3.8 V max), so 5 V signals require a series resistor (e.g., 1.5 kΩ) to limit IIK to ≤±20 mA per Table 4. This is a documented design technique in Nexperia's application notes for mixed-voltage interfacing.

What is the maximum clock frequency supported by 74HC11D,652?

The device has no internal clock; it is combinational logic. Its usable toggle rate is limited by propagation delay and transition time: at VCC = 4.5 V, tpd = 12–25 ns and tt = 7–19 ns, supporting reliable operation up to ~20 MHz for repetitive enable/gating waveforms with clean edges and proper load capacitance (CL ≤ 50 pF).

Does 74HC11D,652 require external pull-up or pull-down resistors on unused inputs?

Yes. Unused inputs must be tied to VCC or GND to prevent floating states that cause increased ICC, noise susceptibility, and potential oscillation. Nexperia recommends hard-wiring unused A/B/C pins to VCC or GND - never leaving them open - as confirmed in Section 6 (Functional description) and Figure 3 (Logic diagram) of the datasheet.
