PI49FCT3807CHEX

Clock Buffers, Drivers Overview

The PI49FCT3807CHEX is a 3.3V Fast CMOS clock driver manufactured by Diodes Incorporated, featuring one input and ten outputs for 1:10 fanout distribution. It operates within a supply voltage range of 3.0V to 3.6V and supports an industrial temperature range of –40°C to +85°C. The device provides ultra-low skew of 0.35ns and a maximum propagation delay of 3.5ns at VCC = 3.3V with a 15pF load. It accepts TTL-compatible inputs and delivers CMOS outputs, ensuring low noise levels and minimal duty cycle distortion.

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'HEX' corresponds to the specific speed grade 'C', the SSOP-20 package, and the tape-and-reel packaging format. Confirm RoHS3 compliance and green manufacturing status as indicated by the 'E' and 'X' suffixes in the official datasheet documentation.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:10 non-inverting clock buffer is required with tight skew specifications. Ensure the design accommodates the 3.3V ±10% supply voltage requirement and the –40°C to +85°C operating temperature range. Verify that the 15pF load condition aligns with the target application's capacitance requirements for the specified 3.5ns propagation delay.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT3807 family of 3.3V Fast CMOS clock drivers. The 'H' suffix denotes the 20-pin 209-mil wide SSOP package, while the 'C' suffix indicates the specific speed grade characterized for a maximum 3.5ns propagation delay. The 'EX' suffix specifies Pb-free, green material composition and tape-and-reel packaging.

Clock Buffers, Drivers Replacement Considerations

PI49FCT3807DHEX offers a faster speed grade with a 3.0ns max propagation delay. PI49FCT3807BHEX provides a 3.8ns max propagation delay. Both maintain the same SSOP-20 package and pinout configuration.
