Nexperia USA Inc. 74HCT10D,653

Overview

74HCT10D,653 from Nexperia is a triple 3-input NAND gate logic IC designed for TTL-level input compatibility in industrial digital control systems. It operates from 4.5 V to 5.5 V, delivers ±4.0 mA output drive at VCC = 4.5 V, exhibits 24 ns typical propagation delay (VCC = 4.5 V, CL = 50 pF), and is qualified from −40 °C to +125 °C in SO14 package. It serves as a core combinational logic element in bus interface conditioning and state-machine enable logic.

For engineers reviewing the 74HCT10D,653 datasheet, 74HCT10D,653 pinout, 74HCT10D,653 application, or 74HCT10D,653 equivalent, this page provides verified functional identity, validated SO14 pin mapping, confirmed TTL-input static/dynamic behavior, and real-world use context for industrial control and legacy system upgrades.

Technical Context

The 74HCT10D,653 implements three independent 3-input NAND gates with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), enabling direct interfacing with legacy 5 V TTL logic families without level-shifting. Each gate features input clamp diodes supporting current-limiting resistor interfaces to voltages exceeding VCC.

Its CMOS output stage provides rail-to-rail swing (VOH ≥ 3.98 V, VOL ≤ 0.26 V at IO = ±4 mA), low static supply current (ICC ≤ 40 μA over full temperature range), and 14 pF power dissipation capacitance-enabling predictable dynamic power estimation via PD = CPD × VCC² × fi × N.

FAQ

Is 74HCT10D,653 compatible with 3.3 V logic systems?

No. The 74HCT10D,653 is specified only for 4.5 V to 5.5 V operation and requires TTL-level inputs (VIH ≥ 2.0 V). Driving it from 3.3 V outputs violates its minimum VIH requirement and may cause unreliable switching or increased ICC. Use 74LVC10 or 74AHC10 for 3.3 V–5 V mixed-voltage designs.

Can 74HCT10D,653 drive LED indicators directly?

Yes, with current-limiting resistors. Its output can sink or source up to 4 mA while maintaining VOL ≤ 0.26 V and VOH ≥ 3.98 V at VCC = 4.5 V. For a typical red LED (VF ≈ 1.8 V), a 330 Ω resistor yields ~8 mA-exceeding rated drive; reduce to 680 Ω for ~4 mA safe operation with visible brightness.

What is the maximum capacitive load for reliable 74HCT10D,653 operation?

The datasheet specifies dynamic performance up to 50 pF (CL = 50 pF, tpd = 24 ns max). Loads exceeding 50 pF increase propagation delay nonlinearly and may cause ringing or logic errors. For 100 pF loads, delay exceeds 35 ns and output rise/fall times degrade beyond 22 ns-add a buffer stage or reduce trace length/capacitance if driving heavy loads.

Does 74HCT10D,653 support hot insertion or live swapping?

No. It lacks hot-swap protection circuitry such as power-up reset, Ioff, or partial-power-down modes. Applying VCC while inputs are biased risks latch-up or excessive ICC due to internal parasitic SCR activation. Always power the device before applying input signals, and use series resistors (≥1 kΩ) during development-stage probing.
