Product details
Overview
NC7ST08P5 from ON Semiconductor is a single 2-input CMOS AND gate with TTL-compatible inputs, designed for high-speed logic interfacing in space-constrained applications. It operates from 4.5 V to 5.5 V, delivers 2 mA sink and −2 mA source output drive, achieves 6 ns typical propagation delay at 5 V/15 pF, and consumes <1 µA quiescent current - enabling low-power, noise-immune signal conditioning in industrial control I/O modules.
For engineers reviewing the NC7ST08P5 datasheet, pinout, applications, or equivalent options, this device is selected for level translation between TTL and CMOS domains, compact board-level logic consolidation, and low-voltage digital signal gating where thermal budget and footprint are critical.
Technical Context
The NC7ST08P5 implements a single 2-input AND function using advanced silicon-gate CMOS technology, ensuring TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) while maintaining rail-to-rail output swing. Its high-gain architecture provides strong noise immunity and reduced sensitivity to input edge rate variations.
It is rated for operation from −40°C to +85°C, supports 15 pF capacitive load at 5 V supply, and features inherent ESD protection diodes on all inputs and output referenced to VCC and GND rails - eliminating need for external clamping in most board-level implementations.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | Wider supply range (1.65–5.5 V), higher drive (±24 mA), but larger SOT-23-5 package (1.6 mm width) | Better suited for mixed-voltage systems or heavier capacitive loads; less optimal for ultra-dense layouts | Select SN74LVC1G08DBVR if 1.65 V operation or >2 mA drive is required; otherwise NC7ST08P5 offers smaller footprint and lower cost |
| MC74VHC1G08DTT1G | Same SC70-5 package, but higher ICC (max 1 µA vs. 10 µA), slightly slower tPD (7.5 ns typ), and no explicit ESD rating in datasheet | Acceptable for non-critical commercial environments; lacks documented ESD robustness for industrial field deployments | Choose MC74VHC1G08DTT1G only for cost-sensitive consumer applications where ESD margin is not mission-critical |
Compared with SN74LVC1G08DBVR and MC74VHC1G08DTT1G, the NC7ST08P5 delivers the smallest SC70 footprint among 5 V-only 2-input AND gates, with verified 2 kV HBM ESD protection and lowest quiescent current - making it optimal for space- and power-constrained industrial control nodes.

FAQ
What is the maximum operating temperature for NC7ST08P5?
The NC7ST08P5 is specified for operation from −40°C to +85°C ambient temperature. Its junction temperature must not exceed 150°C under any condition. For continuous operation at +85°C, ensure θJA remains ≤425°C/W via adequate PCB copper pour and avoid stacking heat-generating components nearby. The NC7ST08P5's thermal performance is validated per JEDEC SC70-5 standards.
Does NC7ST08P5 require external pull-up resistors on its inputs?
No, NC7ST08P5 does not require external pull-up resistors. Its TTL-compatible inputs have defined VIH (2.0 V min) and VIL (0.8 V max) thresholds, and unused inputs must be actively tied HIGH or LOW per datasheet guidance. Floating inputs are prohibited and may cause excessive ICC or metastability. The NC7ST08P5's internal structure does not rely on weak pull-ups for logic interpretation.
Can NC7ST08P5 operate at 3.3 V supply?
No, NC7ST08P5 is not rated for 3.3 V operation. Its recommended operating supply is strictly 4.5 V to 5.5 V. At 3.3 V, VIH and VIL thresholds become undefined, propagation delay increases unpredictably, and output drive falls below specification. For 3.3 V systems, consider SN74LVC1G08DBVR instead. The NC7ST08P5's electrical characteristics are only guaranteed within its stated 4.5–5.5 V range.
What is the meaning of "TTL-compatible inputs" for NC7ST08P5?
"TTL-compatible inputs" means NC7ST08P5 accepts standard TTL logic voltage levels: inputs recognize ≥2.0 V as HIGH and ≤0.8 V as LOW, matching 74LS/74F families. This allows direct connection to legacy TTL outputs without level-shifting circuitry. The NC7ST08P5 achieves this while maintaining CMOS output characteristics - a key advantage for mixed-technology board designs.
Is NC7ST08P5 pin-compatible with other SC70-5 logic gates?
NC7ST08P5 uses the standard SC70-5 pinout (A-B-GND-Y-VCC), which matches industry-standard 2-input logic gates in the same package, such as SN74LVC1G08DBVR and MC74VHC1G08DTT1G. However, pin compatibility alone does not guarantee functional or timing equivalence - always verify logic function, supply range, and drive strength. The NC7ST08P5's pin assignment is fixed per Fairchild/ON Semiconductor documentation and confirmed in its connection diagram.
