Description:
The SN74HC148 devices feature priority decoding of the inputs to ensure that only the highest-order data line is encoded. These devices encode eight data lines to 3-line (4-2-1) binary (octal). Cascading circuitry (enable input EI and enable output EO) has been provided to allow octal expansion without the need for external circuitry. Data inputs and outputs are active at the low logic level.
Features:
- Wide Operating Voltage Range of 2 V to 6 V
- Outputs Can Drive Up To 10 LSTTL Loads
- Low Power Consumption, 80-µA Max ICC
- Typical tpd = 16 ns
- ±4-mA Output Drive at 5 V
- Low Input Current of 1 µA Max
- Encode Eight Data Lines to 3-Line Binary (Octal)
- Applications Include:
- n-Bit Encoding
- Code Converters and Generators
