74FCT16244CTPAG

Overview

The IDT 74FCT16244CTPAG is a 16-bit buffer and line driver belonging to the FCT logic series. It features four independent 4-bit drivers with non-inverting true outputs and three-state capabilities. The device utilizes 0.5-micron CMOS technology, offering high-speed performance with typical output skew under 250ps and low input/output leakage currents. It operates within an extended commercial temperature range of -40°C to +85°C and supports power-off disable for live insertion applications.

Feature Summary

• High-drive outputs capable of sourcing -32mA and sinking 64mA
• Power-off disable feature enables safe live insertion onto active buses
• Low input and output leakage currents maximize system efficiency
• ESD protection exceeds 2000V per MIL-STD-883 Method 3015

Applications

• High-speed memory address buffering
• Clock signal distribution
• Bus transceiver interface drivers
• Receiver and transmitter line driving

Procurement Notes

Verify the specific suffix 'G' against official documentation, as standard datasheets typically list 'CTPAG' or similar variations without explicit confirmation that this suffix alters electrical function. Confirm RoHS compliance status directly with Renesas or IDT archives, as legacy FCT parts may have varying environmental declarations. Ensure the package pitch matches the target PCB footprint requirements.

Selection Notes

Select this component when high drive strength is required for bus loading compared to standard ABT equivalents. The FCT family provides a direct pin-compatible replacement for older bipolar technologies while maintaining lower power consumption. Verify that the 4.5V to 5.5V supply voltage range aligns with the system's power rails and that the TSSOP-48 package fits the available board space constraints.

Part Context

This part belongs to the IDT (now Renesas) 74FCT16244T/AT/CT/ET family of 16-bit buffers. These devices are designed as high-speed, low-power CMOS replacements for ABT functions. The family shares common architectural features including distributed VCC and GND pins to minimize switching noise and optimized PCB layout considerations for high-density designs.

Replacement Considerations

IDT74FCT16244ETPA is a documented alternative within the same product family.
