Diodes Incorporated 74HC00T14-13

Overview

74HC00T14-13 from Diodes Incorporated is a quad 2-input NAND gate IC in TSSOP-14 package, operating from 2.0V to 6.0V supply, delivering 4mA output drive at 4.5V, with Schmitt-trigger inputs and CMOS low-power logic functionality. It implements standard Boolean NAND logic (Y = A·B) and is used in digital control, interface buffering, and signal conditioning within consumer computing peripherals.

For engineers reviewing the 74HC00T14-13 datasheet, 74HC00T14-13 pinout, 74HC00T14-13 application, or 74HC00T14-13 equivalent, key selection criteria include input threshold compatibility across 2–6V rails, propagation delay under 27ns at 4.5V, output drive capability at ±4mA, Schmitt-trigger noise immunity, and TSSOP-14 thermal and board-space constraints.

Technical Context

The 74HC00T14-13 integrates four independent NAND gates on a single silicon die using high-speed CMOS process technology. Each gate features Schmitt-trigger inputs for hysteresis-based noise rejection and push-pull outputs capable of sourcing/sinking up to 4mA at V_CC = 4.5V.

It operates across industrial temperature range (−40°C to +125°C), supports 50pF load-driven propagation delays as low as 9ns (typ.) at 4.5V, and exhibits input leakage <±1μA and quiescent ICC ≤40μA at 6.0V - enabling reliable use in battery-sensitive and noise-prone digital subsystems.

FAQ

Can 74HC00T14-13 operate reliably at 2.0V supply?

Yes. The device is fully specified down to 2.0V: VIH = 1.5V (min), VIL = 0.5V (max), and tPD ≤ 135ns at 2.0V/50pF. Output drive remains functional (IOL/IOH ≥ 2mA), though reduced versus 4.5V operation. This enables direct use with single-cell Li-ion or NiMH battery systems before regulation.

What is the maximum capacitive load the outputs can drive?

The outputs are characterized up to 50pF load per gate, with tPD and tt values guaranteed under that condition. Driving >50pF increases propagation delay nonlinearly and may cause ringing; for >100pF loads, add a series resistor (22–47Ω) near the driver output to dampen reflections without degrading logic thresholds.

How should unused inputs be terminated?

Unused inputs must be tied to VCC or GND - not left floating. Floating CMOS inputs cause increased ICC, potential oscillation, and ESD susceptibility. For NAND gates, tying an unused input to VCC disables that gate's output (forces HIGH), while tying to GND enables it (output follows the other input). Use 10kΩ pull-up/down resistors if current limiting is needed.

Does 74HC00T14-13 support hot-swap or live-insertion?

No. The device lacks bus-hold or I^off protection circuitry. Applying VCC after signal inputs may forward-bias input clamp diodes, causing excessive current flow (>20mA) and potential damage. Always power VCC before applying input signals, and avoid hot-plug scenarios in backplane or modular systems.
