74AVC4T245PW
Overview
The 74AVC4T245PW is a 4-bit, dual-supply translating transceiver designed for asynchronous communication between devices operating at different voltage levels. It features two 2-bit elements, each with independent direction control and output enable inputs, supporting a wide voltage range from 0.8V to 3.6V. The device is optimized for high-performance level shifting with Ioff circuitry to prevent damaging backflow current during partial power-down.
Why Choose This Part
The component supports ultra-low voltage operation down to 0.8V, making it compatible with advanced sub-1V processor cores. Its 3-state outputs and suspend mode functionality ensure minimal power consumption, while the Ioff circuitry protects the system during power-sequencing events. Additionally, it offers robust latch-up performance exceeding 100mA and high ESD protection.
Applications
Key Specifications
Getting Started
To implement this transceiver, connect VCC(A) and VCC(B) to their respective supply rails and ensure decoupling capacitors are placed near the pins. Use the nDIR pins to set data flow direction and the nOE pins to control the high-impedance state of the outputs. Refer to the TSSOP16 land pattern for PCB layout, ensuring traces are kept short to maintain signal integrity at high speeds.
