IC TXRX 4.5V-5.5V 20-SO


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardOctal bus transceiver with 3-state outputs for bidirectional data transfer between two independent 8-bit buses. Operates from 4.5V to 5.5V supply with TTL-compatible logic levels. Commonly used for level shifting and bus buffering in microcontroller systems, memory interfaces, and digital logic applications.
The 1.27mm pin pitch makes hand-soldering this 20-pin SOIC challenging and error-prone. A breakout board brings all pins to standard 0.1" spacing, enabling reliable breadboard prototyping and simplifying development of USB-to-UART interfaces without requiring reflow soldering or specialized equipment.
