74AC16245TTR

Buffers, Drivers, Receivers, Transceivers Overview

The STMicroelectronics 74AC16245TTR is a 16-bit bus transceiver with 3-state outputs. It operates within a supply voltage range of 2V to 6V and features symmetrical output impedance with |IOH| = IOL = 24mA (min). Propagation delay is typically 4.5ns at VCC = 5V, with balanced delays (tPLH ≈ tPHL). Quiescent supply current is 4μA (max) at TA=25°C. The device includes power-down protection on inputs and outputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component status as obsolete in official STMicroelectronics records before procurement planning. Confirm that the TSSOP-48 package matches the design requirements. Ensure compliance with RoHS standards if applicable to the specific manufacturing batch. Review absolute maximum ratings carefully to prevent damage during operation or storage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit bidirectional interface is required with a single supply voltage between 2V and 6V. It is suitable for applications needing high-speed data transfer with low power dissipation. Consider the TSSOP-48 package constraints regarding thermal management and board space. Verify compatibility with existing logic families in the system design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC series of advanced CMOS logic devices manufactured by STMicroelectronics. It is functionally compatible with the standard 74HC16245 but offers higher speed performance.
