Pinout
Key features include:
- Two 4-bit buffers/line drivers with separate output-enable (OE) inputs.
- High-speed CMOS device with low power consumption.
- Output capability of driving up to 15 LSTTL loads.
- Wide operating voltage range from 2V to 6V.
- 3-state outputs for bus-oriented applications.
The pin configuration is as follows:
- Pins 1, 10: Output Enable (OE)
- Pins 2-5, 7-9: Data Inputs (A1-A8)
- Pins 18-11: Data Outputs (Y1-Y8)
- Pin 20: VCC (Power Supply)
- Pin 10: GND (Ground)
The device operates as two separate 4-bit sections, controlled by individual output-enable signals. When OE is low, the corresponding buffer outputs are enabled, and the device transmits the data from inputs to outputs. When OE is high, the outputs are in a high-impedance state.
