Diodes Incorporated 74AVC4T 4-Bit Dual Power Supply Translating Buffer

Diodes Incorporated 74AVC4T 4-Bit Dual Power Supply Translating Buffers with three-state outputs are designed for high-speed, low-voltage logic level translation. These Diodes Inc. 74AVC4T devices support bidirectional voltage-level shifting between two logic levels, such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V, ideal for mixed-voltage system designs. Featuring dual VCC rails and direction control, these buffers enable efficient data transfer between buses operating at different voltages. The series offers high drive capability, low propagation delay, and low power consumption, ensuring reliable performance in portable electronics, computing, and communication applications. Available in a compact TSSOP16 package, these devices are RoHS-compliant and optimized for space-constrained designs.
