Product Summary
The SN54LS148J is a priority encoder. The applications of the device include n-Bit Encoding and Code Converters and Generators. The SN54LS148J features priority decoding of the inputs to ensure that only the highest-order data line is encoded. The SN54LS148J encodes eight data lines to three-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. For all types, data inputs and outputs are active at the low logic level. All inputs are buffered to represent one normalized Series 54/74 or 54/74LS load, respectively.
Parametrics
SN54LS148J absolute maximum ratings: (1)Supply voltage, VCC: 7 V; (2)Input voltage, VI: 7 V; (3)Inter-emitter voltage: 5.5 V; (4)Package thermal impedance, θJA: 73℃/W; (5)Storage temperature range, Tstg: -65 to 150℃.
Features
SN54LS148J features: (1)Encode 8 Data Lines to 3-Line Binary (Octal).
