Nexperia USA Inc. 74HC08D,652

Overview

74HC08D,652 from Nexperia is a quad 2-input AND gate in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, propagation delay of 7–27 ns (VCC = 2.0–6.0 V), and guaranteed operation from −40 °C to +125 °C. It integrates input clamp diodes enabling safe interfacing to voltages exceeding VCC using current-limiting resistors, and is used in digital logic control, address decoding, and enable gating in industrial microcontroller peripherals.

For engineers reviewing the 74HC08D,652 datasheet, 74HC08D,652 pinout, 74HC08D,652 application, or 74HC08D,652 equivalent, key selection criteria include supply voltage range compatibility (2.0–6.0 V), input logic level type (CMOS), propagation delay at target VCC and load, thermal rating (−40 °C to +125 °C), and SO14 package footprint constraints.

Technical Context

This device implements four independent 2-input AND logic functions in a single monolithic CMOS IC. Each gate features symmetric input structure with integrated clamp diodes referenced to VCC and GND, supporting robust level-shifting and overvoltage-tolerant interfacing without external protection components.

It complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, delivers high noise immunity (>40% VCC), and meets Class II Level B latch-up performance (>100 mA). Static and dynamic characteristics are fully specified across −40 °C to +125 °C ambient temperature.

FAQ

Can 74HC08D,652 operate reliably at 2.0 V supply?

Yes. The device is fully specified from 2.0 V to 6.0 V, with guaranteed propagation delay ≤90 ns and output drive capability (VOH ≥1.5 V, VOL ≤0.1 V) at VCC = 2.0 V and −40 °C to +125 °C. Input thresholds scale with VCC (VIH ≥1.5 V, VIL ≤0.5 V), ensuring noise-immune operation even at minimum supply.

Does 74HC08D,652 require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs must be tied HIGH or LOW via direct connection to VCC or GND-not through resistors-to prevent floating nodes that cause increased ICC, oscillation, or localized heating. CMOS inputs draw negligible current (<1 μA), so hard-wiring avoids unnecessary power loss and signal integrity risk.

What is the maximum capacitive load this device can drive while maintaining specified timing?

The datasheet specifies dynamic parameters (tpd, tt) at CL = 50 pF. While it can drive heavier loads, propagation delay increases linearly with capacitance-e.g., tpd ≈ 18 ns at CL = 50 pF (VCC = 4.5 V), rising to ~35 ns at CL = 100 pF. For timing-critical paths, keep total load (trace + input + probe) ≤50 pF or recalculate setup/hold margins accordingly.

Is the SO14 package of 74HC08D,652 compatible with lead-free reflow profiles?

Yes. The SOT108-1 package is rated for standard IPC/JEDEC J-STD-020D lead-free reflow, with peak temperature up to 260 °C for ≤60 seconds. Its moisture sensitivity level (MSL) is 1-unlimited floor life at ≤30 °C/60% RH-eliminating bake requirements prior to assembly.
