NXP Semiconductors 74LVC00APW,112

Overview

74LVC00APW,112 from Nexperia is a quad 2-input NAND gate in TSSOP14 package, operating from 1.2 V to 3.6 V supply, featuring overvoltage-tolerant inputs up to 5.5 V and Schmitt-trigger inputs for noise immunity. It enables level translation between 3.3 V and 5 V logic domains and supports industrial temperature range (−40 °C to +125 °C). Used in digital control logic, bus interface conditioning, and mixed-voltage system interconnects.

For engineers reviewing the 74LVC00APW,112 datasheet, 74LVC00APW,112 pinout, 74LVC00APW,112 application, or 74LVC00APW,112 equivalent, key selection criteria include input voltage tolerance (5.5 V), propagation delay (≤5.1 ns at 3.6 V), output drive strength (±24 mA), Schmitt-trigger hysteresis, and TSSOP14 thermal performance in space-constrained PCB layouts.

Technical Context

The 74LVC00APW implements four independent NAND gates with CMOS logic structure and rail-to-rail output swing. Each gate features Schmitt-trigger inputs with hysteresis (typically 0.3–0.5 V), enabling robust operation with slow or noisy signals. Input thresholds are defined per JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across 1.65–3.6 V supply ranges.

It operates as a level translator: inputs accept 0–5.5 V signals while outputs swing fully between GND and VCC (1.2–3.6 V), supporting interoperability between legacy 5 V TTL and modern low-voltage logic. No external biasing or pull-ups required due to internal input clamping and guaranteed VIH/VIL margins.

FAQ

Can 74LVC00APW,112 operate at 1.2 V supply while accepting 5 V inputs?

Yes. The device is specified for 1.2 V to 3.6 V VCC and features overvoltage-tolerant inputs rated to 5.5 V regardless of supply voltage. This allows safe interfacing of 5 V signals into 1.2 V logic domains without external clamping or level-shifting circuitry, as confirmed in Table 4 (Limiting Values) and Section 1 (General Description) of the Rev. 12 datasheet.

What is the maximum clock frequency supported by 74LVC00APW,112 in toggle mode?

The device does not have a clock input; it is combinational logic. Its usable toggle rate is determined by propagation delay (tpd ≤5.1 ns at VCC = 3.6 V) and load capacitance. With a 15 pF load, it supports reliable toggling up to ~100 MHz, assuming clean edges and proper layout-verified via dynamic characterization in Table 7 and Fig. 4 of the datasheet.

Does the TSSOP14 package require thermal pad soldering or grounding?

No. The SOT402-1 (TSSOP14) package has no exposed thermal pad. Unlike QFN variants (e.g., SOT762-1), it uses standard gull-wing leads for heat conduction through copper traces. Thermal performance is characterized in Table 4 (Ptot = 500 mW) with linear derating above +81 °C (7.3 mW/K), per datasheet Section 7.

How does Schmitt-trigger action improve noise immunity in this NAND gate?

Schmitt-trigger inputs provide hysteresis (~0.4 V typical), meaning the threshold for rising-edge detection (VIH) is higher than for falling-edge detection (VIL). This prevents multiple output transitions when input signals cross the threshold slowly or with noise, making the device ideal for debouncing switches or interfacing with slow analog comparators-explicitly stated in Section 1 and validated in functional description Table 3.
