STMicroelectronics M74HC10B1R

Overview

M74HC10B1R from STMicroelectronics is a high-speed CMOS triple 3-input NAND gate in a 14-pin plastic DIP package, operating from 2V to 6V supply, with typical propagation delay of 8ns at 6V, symmetrical output drive (±4mA), and quiescent current ≤1µA at 25°C - used in digital logic control, address decoding, and enable gating in industrial microcontroller interfaces.

For engineers reviewing the M74HC10B1R datasheet, M74HC10B1R pinout, M74HC10B1R application, or M74HC10B1R equivalent, key selection criteria include VCC range compatibility (2–6V), noise immunity (≥28% VCC), balanced tPLH/tPHL delays, and DIP-14 through-hole mounting for prototyping and legacy board designs.

Technical Context

The M74HC10B1R implements three independent 3-input NAND gates using silicon gate C2MOS technology, each with buffered output stages to ensure stable switching and high noise immunity. Its input protection circuits guard against ESD and transient overvoltage, supporting robust operation across -55°C to +125°C.

It delivers symmetrical output impedance (|IOH| = IOL ≥ 4mA) and balanced propagation delays (tPLH ≅ tPHL), enabling predictable timing in combinational logic chains. The device meets standard 74-series logic function and pinout compatibility while offering improved speed and lower power versus legacy 74LS variants.

FAQ

Is M74HC10B1R compatible with 5V TTL logic inputs?

Yes - its VIH minimum is 3.15V at VCC = 4.5V and 4.2V at VCC = 6V, exceeding standard TTL's 2.0V high-level threshold. Inputs tolerate up to VCC + 0.5V, allowing safe interfacing with 5V TTL outputs without level shifters.

What is the maximum fanout capability of M74HC10B1R at 6V?

At VCC = 6V, each output can sink/source ≥4mA. With typical 74HC input current ≤1µA and C_IN ≤10pF, it reliably drives ≥20 downstream 74HC inputs or 10 74LS inputs without timing degradation or voltage droop.

Does M74HC10B1R require external pull-up resistors on outputs?

No - it features push-pull CMOS outputs, not open-drain. Pull-ups are unnecessary unless implementing wired-AND logic or interfacing with legacy NMOS devices; unused inputs must be tied HIGH or LOW to prevent floating.

Can M74HC10B1R operate reliably at 2.0V supply?

Yes - guaranteed operation down to 2.0V with VIH ≥1.5V and VOL ≤0.1V at 20µA load. Propagation delay increases to 27ns (typ.), but logic levels remain valid for ultra-low-power sensor nodes and energy-harvesting systems.
