Diodes Incorporated 74AHC00T14-13

Overview

74AHC00T14-13 from Diodes Incorporated is a quad 2-input NAND gate IC in TSSOP-14 package, operating from 2.0V to 5.5V supply, with 5.5V-tolerant inputs, 8 mA output drive at 4.5V, and Schmitt-trigger inputs for noise immunity-used in voltage translation and general-purpose logic interfacing in PC peripherals and consumer electronics.

For engineers reviewing the 74AHC00T14-13 datasheet, 74AHC00T14-13 pinout, 74AHC00T14-13 application, or 74AHC00T14-13 equivalent, key selection criteria include input voltage tolerance (5.5V), propagation delay (≤7.0 ns at 5V/50pF), output drive capability (±8 mA), CMOS power efficiency (<40 µA ICC max), and TSSOP-14 thermal and board-space advantages over SO-14.

Technical Context

This device implements four independent Boolean NAND functions (Y = A·B) using advanced CMOS process technology. Each gate features Schmitt-trigger inputs for hysteresis-based noise rejection and supports mixed-voltage signal translation between 3.3V and 5V domains without level shifters.

It operates across industrial temperature range (–40°C to +125°C) with guaranteed performance at VCC = 2.0V–5.5V, and meets JESD22 ESD standards (2 kV HBM, 1 kV CDM). Absolute maximum ratings allow transient input voltages up to 7.0V without damage.

FAQ

Can 74AHC00T14-13 operate reliably at 2.0V supply?

Yes. The device is fully specified down to 2.0V VCC, with guaranteed VIH = 1.5V and VOL ≤ 0.1V at IO = 50 µA. Propagation delay increases to 14.5 ns (max) at 2.0V/50pF, but logic functionality remains intact across the full industrial temperature range.

Is input hysteresis present on all four gates?

Yes. All four inputs feature identical Schmitt-trigger action with typical hysteresis of 0.3V, confirmed by VIH = 1.5V and VIL = 0.5V at VCC = 2.0V, and consistent across temperature and supply voltage per datasheet Figure 3 and Table 5.

What is the maximum capacitive load this device can drive?

The datasheet specifies switching characteristics up to CL = 50pF. While not explicitly rated beyond that, the ±8 mA output drive suggests safe operation with ≤75pF total load (including trace capacitance) at 5V, assuming tPD degradation remains within system timing margins.

Does this part require external pull-up or pull-down resistors on unused inputs?

Yes. Per Recommended Operating Conditions Note 5, unused inputs must be tied to either VCC or GND to prevent floating states, oscillation, and excess current draw. Leaving inputs unconnected risks increased ICC and potential logic instability due to internal node coupling.
