SN74ALVCH245DGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH245DGVR is an octal bus transceiver with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features a maximum propagation delay of 3.4 ns at 3.3 V. The device provides ±24-mA output drive capability and incorporates active bus-hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors. It utilizes a TVSOP-20 package and supports asynchronous communication between data buses in both directions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-20 package and tape-and-reel carrier configuration. Confirm that the RoHS status and lead finish (NIPDAU) align with assembly requirements. Ensure the operating temperature range of -40°C to 85°C meets environmental specifications for the intended application.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage operation between 1.65 V and 3.6 V with high-speed data transfer capabilities. The inclusion of bus-hold functionality simplifies design by removing external resistor requirements. Consider the TVSOP-20 package constraints regarding thermal impedance and PCB layout guidelines provided in the datasheet.
