Design a Custom BoardAbout This Component
Octal transparent D-type latch with 3-state outputs in 20-pin SO package. Operates at 4.5-5.5V with 21ns typical propagation delay and ±6mA output drive. Eight independent latches with TTL-compatible inputs, suitable for buffer registers, I/O ports, and bidirectional bus drivers.
Package: SOIC-20W (7.5mm wide) · 20 pins
Why does this need a breakout?
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.
