What are the key features of SN74AVCH8T245PWR?
- Dual-supply operation: VCCA 1.2V–3.6V and VCCB 1.65V–5.5V for mixed-voltage interfacing
- 8-bit bidirectional data flow controlled by DIR and OE pins
- 24mA output drive strength for robust bus driving
- Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
- Low power consumption with IOFF feature supporting partial-power-down applications
- Available in 24-pin TSSOP package (PWR) for space-constrained PCB designs
What is SN74AVCH8T245PWR used for?
The SN74AVCH8T245PWR is widely used in mixed-voltage digital systems where logic level translation between 1.2V, 1.8V, 2.5V, 3.3V, and 5V domains is required. It is ideal for microprocessor/microcontroller bus buffering, memory interface level shifting, and I/O expansion in portable consumer electronics, industrial control systems, and communication equipment. Its dual-supply architecture and high drive strength make it a reliable choice for high-speed data bus applications in server boards, FPGAs, and DSP systems.

Frequently Asked Questions
What voltage levels does the SN74AVCH8T245PWR support?
The SN74AVCH8T245PWR supports VCCA from 1.2V to 3.6V and VCCB from 1.65V to 5.5V, enabling bidirectional level translation between common logic families including 1.2V, 1.8V, 2.5V, 3.3V, and 5V systems.
How do the DIR and OE pins control data direction on the SN74AVCH8T245PWR?
The DIR pin selects data flow direction: when DIR is HIGH, data flows from the B port to the A port; when DIR is LOW, data flows from A to B. The OE pin (active LOW) enables or disables all outputs — pulling OE HIGH puts all outputs in a high-impedance state, isolating the bus.
What is the package type and pin count of the SN74AVCH8T245PWR?
The SN74AVCH8T245PWR comes in a 24-pin TSSOP (Thin Shrink Small Outline Package) with a 4.4mm body width and 0.65mm pin pitch, making it suitable for compact, surface-mount PCB designs requiring minimal board area.
Can the SN74AVCH8T245PWR be used in partial-power-down applications?
Yes. The SN74AVCH8T245PWR features an IOFF characteristic that disables the outputs when either supply is at ground, preventing damaging backflow current. This makes it safe for use in systems where one voltage rail may be powered down independently.
What are common applications for the SN74AVCH8T245PWR?
Common applications include mixed-voltage bus buffering between microcontrollers and peripherals, memory interface level shifting in DDR systems, I/O expansion in FPGAs, and voltage translation in industrial control, telecom, and portable consumer electronics where multiple supply voltages coexist.
