PI74AVC164245AAE

Translators, Level Shifters Overview

The PI74AVC164245AAE is a 16-bit dual-octal noninverting bus transceiver manufactured by Diodes Incorporated. It features two separate supply rails: VCCA operating at 1.8V to 2.5V and VCCB set at 3.3V, enabling bidirectional voltage translation between these levels. The device utilizes advanced 0.35 micron CMOS technology for high performance and low power consumption. It provides 3-state outputs controlled by direction (DIR) and output-enable (OE) inputs. The component supports industrial operation temperatures ranging from -40°C to +85°C and is housed in a 48-pin TSSOP package.

Translators, Level Shifters Feature Summary

• Supports asynchronous communication with bidirectional data transfer between 1.8-2.5V and 3.3V environments
• Provides high impedance state during power up or power down when OE input is tied to VCC via pullup resistor
• Designed for low voltage operation using advanced 0.35 micron CMOS technology

Translators, Level Shifters Applications

• Asynchronous communication between data buses
