Pinout
This IC comes in a 20-pin package, specifically a TSSOP (Thin Shrink Small Outline Package). Here is a brief description of its pin functions:
- Inputs/Outputs:
- 8 data inputs (A1 to A8) and 8 corresponding data outputs (Y1 to Y8).
- Control Pins:
- Two output enable pins (1OE and 2OE) that control the output state; when these are low, the corresponding outputs are enabled, and when high, they are in a high-impedance state.
- Power Supply:
- VCC: Power supply pin.
- GND: Ground pin.
This configuration allows the device to act as a buffer and driver, providing strong and reliable signal transmission while minimizing loading effects on the input signals.
