onsemi NC7ST00P5X-L22057

Overview

NC7ST00P5X-L22057 from onsemi is a single 2-input high-performance CMOS NAND gate with TTL-compatible inputs, 2 mA sink/source output drive, <7 ns typical propagation delay at 5 V/15 pF, and operation across −40 °C to +85 °C. It serves as a logic-level translator and signal combiner in low-power digital control circuits.

For engineers reviewing the NC7ST00P5X-L22057 datasheet, pinout, applications, or equivalent options, key selection criteria include input compatibility with legacy TTL, output drive capability for fan-out to HC/HCT loads, SC-88A package footprint constraints, and quiescent current under 1 µA at 5.5 V.

Technical Context

The NC7ST00P5X-L22057 implements a standard NAND Boolean function (Y = A·B) using advanced silicon-gate CMOS technology. Its TTL-compatible inputs accept VIH ≥ 2.0 V and VIL ≤ 0.8 V over 4.5–5.5 V supply, enabling direct interfacing with 5 V TTL and NMOS logic families.

It delivers balanced output drive (±2 mA), exhibits high noise immunity due to high-gain circuitry, and integrates ESD protection diodes on all I/O pins referenced to VCC and GND. Propagation delay remains stable across temperature (−40 °C to +85 °C) and supply voltage (4.5–5.5 V).

FAQ

What logic function does the NC7ST00P5X-L22057 implement?

The NC7ST00P5X-L22057 implements a standard 2-input NAND Boolean function (Y = A·B). Its truth table shows HIGH output for any input combination except when both A and B are HIGH. This function is used for basic logic inversion, enable/disable control, and signal masking in digital systems. The NC7ST00P5X-L22057 performs this operation with TTL-compatible input thresholds and balanced ±2 mA output drive.

Is the NC7ST00P5X-L22057 pin-compatible with older 74LS00 devices?

No, the NC7ST00P5X-L22057 is not pin-compatible with through-hole 74LS00 (14-pin DIP) due to its 5-pin SC-88A package. However, its logic function, input voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and 5 V supply range make it a functional drop-in replacement in circuit design-provided the PCB layout accommodates the smaller SC-88A footprint. The NC7ST00P5X-L22057 retains identical Boolean behavior while improving speed and reducing quiescent current.

What is the maximum recommended load capacitance for the NC7ST00P5X-L22057?

The NC7ST00P5X-L22057 is characterized up to 50 pF load capacitance, with propagation delay increasing from 6.3 ns (typ, CL = 15 pF) to 11.5 ns (typ, CL = 50 pF) at VCC = 4.5 V. For reliable sub-10 ns timing, keep total capacitive load-including trace, probe, and downstream input capacitance-below 30 pF. Exceeding 50 pF may cause excessive transition time or output waveform distortion. The NC7ST00P5X-L22057's output drive remains stable within its ±2 mA specification across this range.

Does the NC7ST00P5X-L22057 require external pull-up resistors on its inputs?

No, the NC7ST00P5X-L22057 does not require external pull-up resistors on its inputs because it has no internal pull-ups. However, unused inputs must be actively tied HIGH or LOW-never left floating-to prevent increased ICC, oscillation, or undefined output states. A 10 kΩ pull-up or pull-down resistor is acceptable if needed for system-level signal routing. The NC7ST00P5X-L22057's TTL-compatible inputs ensure compatibility with either driven or resistively terminated sources.

What is the thermal resistance (θJA) of the NC7ST00P5X-L22057 in SC-88A package?

The NC7ST00P5X-L22057 in SC-88A package has a junction-to-ambient thermal resistance (θJA) of 377 °C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad with no thermal vias. In practice, adding two or more thermal vias beneath the exposed pad (if present) or increasing copper area can reduce effective θJA by 20–40%. The NC7ST00P5X-L22057's low power dissipation (<1 µA ICC) means self-heating is negligible in most applications, even at full ambient temperature.
