Pinout
This device comes in a 20-pin TSSOP (Thin Shrink Small Outline Package). The pins are configured as follows:
- 8 input pins: 1A1 to 1A4 and 2A1 to 2A4
- 8 corresponding output pins: 1Y1 to 1Y4 and 2Y1 to 2Y4
- 2 enable pins: 1OE (Output Enable for outputs 1Y1 to 1Y4) and 2OE (Output Enable for outputs 2Y1 to 2Y4)
- 1 V_CC pin for the power supply
- 1 GND pin for ground
The output enable pins (1OE and 2OE) control whether the outputs are enabled or in a high-impedance state, thus allowing for effective operation in bus-oriented systems by preventing bus contention. The device operates with a supply voltage typically ranging from 1.65 V to 3.6 V, making it suitable for various low-voltage applications.
