74ABT374CMSA

Flip Flops Overview

The onsemi 74ABT374CMSA is an octal D-type flip-flop belonging to the ABT logic series, housed in a 20-SSOP surface-mount package. It features eight non-inverting D-type inputs with a common buffered positive edge-triggered clock and output enable. The device provides three-state outputs with high drive capability, specified at 64 mA sink and 32 mA source currents. Operating within a supply voltage range of 4.5 V to 5.5 V, it exhibits a maximum propagation delay of 5 ns at 5 V with 50 pF load. The component supports a clock frequency up to 200 MHz and functions reliably across an industrial temperature range of -40°C to +85°C.

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation prior to integration. Ensure handling procedures align with moisture sensitivity level requirements. Validate that the specific SSOP-20 package variant matches design constraints. Review end-of-life notices as availability may be restricted.

Flip Flops Selection Notes

Select this component for designs requiring high-speed octal latching with strong output drive. The ABT series offers superior performance compared to standard TTL equivalents. Verify that the 20-SSOP footprint fits the PCB layout. Consider thermal management within the specified operating temperature range. Ensure supply voltage stability between 4.5 V and 5.5 V for optimal timing characteristics.
