74AC16244TTR

Buffers, Drivers, Receivers, Transceivers Overview

The 74AC16244TTR is a 16-bit bus buffer with 3-state outputs manufactured by STMicroelectronics. It operates within a supply voltage range of 2V to 6V and features high-speed performance with a typical propagation delay of 4.5ns at 5V. The device provides symmetrical output impedance, ensuring |IOH| = IOL = 24mA (min). It includes power-down protection on inputs and improved latch-up immunity. The component is housed in a TSSOP-48 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the obsolete status of this component before design finalization. Confirm that the TSSOP-48 package dimensions align with current PCB layout requirements. Ensure that the 2V to 6V operating voltage range meets system specifications. Check for updated replacement part numbers from STMicroelectronics or authorized distributors.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 16-bit non-inverting buffering with 3-state control. Consider the 4.5ns typical propagation delay for high-speed data paths. Verify compatibility with existing logic families given the 2V to 6V operating range. Evaluate the TSSOP-48 package constraints against available board space.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC series of advanced CMOS logic devices. It functions as a 16-bit bus buffer, distinct from octal variants like the 74AC244. The device utilizes sub-micron silicon gate and double-layer metal wiring C2MOS technology for enhanced performance and density compared to standard AC series components.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible replacements such as the 74ACT16244 if TTL-compatible inputs are required. Verify availability of alternative manufacturers offering equivalent 16-bit bus buffers in TSSOP-48 packages.
