SN74AS874NT

Flip Flops Overview

The SN74AS874NT is a dual 4-bit D-type edge-triggered flip-flop from the Texas Instruments SN74AS series. It operates within a supply voltage range of 4.5 V to 5.5 V and features Schottky-clamped inputs for high noise immunity. The device provides non-inverting outputs with a propagation delay of 9 ns and supports output currents of -15 mA (high) and 48 mA (low). Packaged in a 20-pin SOIC, it functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Dual 4-bit architecture providing eight independent D-type flip-flops in a single package
• Schottky clamping on inputs ensures high noise immunity and fast switching speeds
• Non-inverting outputs deliver strong drive capability suitable for bus-oriented applications

Flip Flops Applications

• High-speed data storage registers in digital systems
• Parallel-to-serial conversion circuits
• Bus-oriented memory structures requiring fast clocking

Flip Flops Procurement Notes

Verify the specific suffix 'NT' against the manufacturer's current ordering guide to confirm the exact tape-and-reel packaging configuration and pin compatibility. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the datasheet revision date to confirm any recent electrical parameter updates or pinout changes before finalizing procurement specifications.

Flip Flops Selection Notes

Select this component when system design requires high-speed data latching with significant output drive strength. The SN74AS series offers superior speed compared to standard TTL but consumes more power than LS variants. Consider thermal management due to higher static current consumption inherent to the AS logic family. Verify that the 5V supply rail stability matches the device's strict voltage limits for reliable operation.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74AS (Advanced Schottky) logic family, known for high-speed performance. It serves as a digital storage element within larger integrated circuit systems. The device is designed for through-hole or surface-mount integration depending on the specific package variant, facilitating its use in industrial and commercial electronic control units.
