74AHCT08PW,112

Overview

The Nexperia 74AHCT08PW,112 is a quad 2-input AND gate in the AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level input signals. The device features overvoltage tolerant inputs up to 5.5 V, allowing use as translators in mixed-voltage environments. It utilizes a TSSOP14 (SOT402-1) package with 14 leads and a body width of 4.4 mm. Static characteristics include an input leakage current maximum of 2.0 μA at -40 °C to +125 °C. Dynamic performance specifies a propagation delay of 9.0 ns maximum at 5.0 V with 50 pF load capacitance across the full temperature range.

Feature Summary

• Quad 2-input AND logic function
• TTL-compatible input levels
• Overvoltage tolerant inputs
• Schmitt-trigger action on all inputs

Applications

• Mixed voltage translation between CMOS and TTL domains
• Digital signal processing logic gates
• General-purpose logic control circuits

Procurement Notes

Verify the specific ordering suffix ',112' against the manufacturer's current datasheet to confirm the exact tape-and-reel quantity and packaging variant. Confirm that the TSSOP14 package designation matches the required footprint for the target PCB layout. Ensure the component status is checked directly with Nexperia or authorized distributors, as product availability and lifecycle status can change without prior notice.

Selection Notes

Select this component when TTL-level interface compatibility is required within a 5 V system. The AHCT series provides balanced propagation delays suitable for general digital applications. Verify that the operating environment remains within the specified -40 °C to +125 °C temperature range. Consider the TSSOP14 package dimensions if board space constraints are a primary design factor compared to standard SO packages.

Part Context

This part belongs to the Nexperia 74AHC/AHCT logic family, which offers high-speed CMOS performance with TTL-compatible inputs. The 'AHCT' designation specifically indicates compatibility with standard TTL logic levels while maintaining CMOS power consumption benefits. The 'PW' suffix identifies the Thin Shrink Small Outline Package (TSSOP), providing a compact surface-mount solution for modern electronic assemblies.

Replacement Considerations

Direct functional equivalents include other manufacturers' 74AHCT08 devices in TSSOP14 packages. Cross-reference pinouts and electrical specifications carefully, particularly regarding input voltage thresholds and output drive capabilities, to ensure compatibility with existing circuit designs.
