IDT49FCT805PY

Clock Buffers, Drivers Overview

The IDT49FCT805PY is a non-inverting buffer and clock driver utilizing advanced dual metal CMOS technology. It comprises two independent output banks, each providing a 1:5 fanout from standard TTL-compatible inputs. The device features rail-to-rail output swing for improved noise margins and includes a dedicated 'heartbeat' monitor output identical to the primary outputs for diagnostics and PLL driving. Designed for high-speed clock distribution, it guarantees low skew of less than 700ps maximum and low duty cycle distortion under 1ns. The component supports commercial temperature ranges.

Clock Buffers, Drivers Feature Summary

• Dual independent output banks with 1:5 fanout per bank
• Guaranteed low skew < 700ps (max) and low duty cycle distortion < 1ns (max)
• Rail-to-rail output voltage swing with high drive capability (-24mA IOH, +64mA IOL)
• Includes 'heartbeat' monitor output for diagnostics and PLL driving

Clock Buffers, Drivers Applications

• High-speed clock distribution where signal quality and skew are critical
• Single point-to-point transmission line driving
• Address distribution requiring multiple receivers with low skew

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. The datasheet indicates that non-green parts reached End-of-Life on May 13, 2010. Ensure compatibility with existing board designs regarding Pin 8, which may be internally connected to GND on older devices but should be connected to GND at the board level for all products.

Clock Buffers, Drivers Selection Notes

Select the IDT49FCT805A variant if industrial temperature operation (-40°C to +85°C) is required, as the base model covers the commercial range (0°C to +70°C). Confirm power supply requirements match the specified VCC range. Verify that the load capacitance and termination resistance align with the switching characteristics test conditions to ensure timing performance meets system specifications.
