Product details

What this 8-bit D-type flip-flop brings to a bus

The Texas Instruments SN74ABT374APW is an 8-bit D-type flip-flop with tri-state, non-inverted outputs, clocked on the positive edge. It belongs to the 74ABT family — Advanced BiCMOS Technology — which balances the speed of ABT with lower power draw than pure bipolar logic. The 200 MHz clock frequency and 6.6 ns propagation delay at 5V, 50 pF place it in the fast register tier, suited for buffering address/data buses, pipeline stages, or status-latch applications where the bus must be isolated from the core logic during read cycles. Output drive is rated at 32 mA source and 64 mA sink.

Frequently asked questions

What is the difference between SN74ABT374APW and SN74ABT374APWR?

The difference is packaging: SN74ABT374APW ships in Tube, while SN74ABT374APWR is the Tape & Reel variant. The silicon and electrical specs are identical.

What are the equivalents or replacement for SN74ABT374APW?

Within the same 74ABT family, the SN74ABT377DW is a similar 8-bit D-type flip-flop but with a different output control scheme. For a functional second-source with a lower clock speed, the 74F374SCX-NS (140 MHz) is a positive-edge triggered D-type in a similar surface-mount package, though it is rated for commercial temperature (0°C to 70°C) only.

What is the lead time for SN74ABT374APW?

Lead time is confirmed at quote time when you submit an RFQ. As an active, widely stocked part, typical lead times are manageable through independent distribution channels.

Can SN74ABT374APW replace 74ABT374?

Yes — the SN74ABT374APW is a specific ordering code within the 74ABT374 function. The 'APW' suffix denotes the 20-TSSOP package in Tube. If your BOM calls for a generic 74ABT374, verify the package and temperature grade match; this part covers the industrial temperature range and surface-mount footprint.
