Product details

Overview

74HCT10DB,112 from Nexperia is a triple 3-input NAND gate IC operating at 4.5–5.5 V supply, with typical propagation delay of 18 ns at 5 V, fan-out of 10 LSTTL loads, and CMOS input compatibility. It performs logic-level signal inversion and combination in digital control buses and address decoding circuits.

For engineers reviewing the 74HCT10DB,112 datasheet, 74HCT10DB,112 pinout, 74HCT10DB,112 application, or 74HCT10DB,112 equivalent, key selection criteria include guaranteed TTL-compatible output drive, low-power HCMOS input structure, and SO-14 package suitability for space-constrained PCB layouts.

Technical Context

This device implements three independent 3-input NAND gates using silicon-gate CMOS technology. Each gate features buffered outputs, symmetric rise/fall times (typ. 17 ns), and input thresholds aligned to TTL voltage levels (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V).

It operates within industrial temperature range (−40 °C to +125 °C) and meets JEDEC standard JESD78A for latch-up immunity (>100 mA). The logic function conforms to IEC 60617-12 and ANSI/IEEE Std 91-1984.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-input NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HCT10DR	SO-14 package, same logic and timing specs; TI part has tighter V_OH min (4.4 V vs. 4.2 V at I_O = −4 mA)	Valid for TI-based designs with stricter high-level output margin requirements	Select when sourcing from TI-authorized channels or when V_OH margin above 4.4 V is required
74HCT10N,623	DIP-14 through-hole package; identical electrical specs but different thermal resistance and mounting method	Suitable for prototyping, educational kits, or legacy wave-soldered assemblies	Choose for hand-soldered evaluation or where SO-14 reflow is unavailable

Compared with SN74HCT10DR and 74HCT10N,623, the 74HCT10DB,112 offers optimized surface-mount reliability for automated production, balanced drive strength for mixed-logic systems, and extended temperature capability critical for under-hood and factory-floor deployments.

FAQ

What is the maximum clock frequency supported by 74HCT10DB,112?

The 74HCT10DB,112 is a combinational logic device without an internal clock. Its usable toggle rate depends on propagation delay and system loading. With 18 ns typical t_PD and 50 pF load, it supports reliable operation up to approximately 25 MHz in feedback-free configurations, assuming clean signal edges and proper termination.

Can 74HCT10DB,112 drive LEDs directly?

No. Its output drive is rated ±4 mA at V_CC = 4.5 V, insufficient for standard indicator LEDs requiring 10–20 mA. It can drive LED anodes via a current-limiting resistor only if forward current is restricted to ≤4 mA, resulting in very low brightness. Use a dedicated LED driver or transistor buffer for full-brightness indication.

Is 74HCT10DB,112 compatible with 3.3 V microcontrollers?

Inputs accept 3.3 V logic high as valid (V_IH ≥ 2.0 V), but outputs swing to V_CC (5 V), risking damage to 3.3 V-only inputs. Direct connection requires level-shifting or series resistors. For native 3.3 V systems, consider 74LVC10 or 74AHC10 instead.

Does 74HCT10DB,112 require external pull-up resistors on inputs?

No. Inputs have CMOS structure with high impedance and defined TTL-compatible thresholds. Unused inputs must be tied to V_CC or GND to prevent floating states and unintended switching; pull-up resistors are unnecessary and may increase power consumption unnecessarily.
