Product Summary
The SN74HC148N is a 3-line priority encoder. It features priority decoding of the inputs to ensure that only the highest-order data line is encoded. The SN74HC148N encodes 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.
Parametrics
SN74HC148N absolute maximum ratings: (1)Supply voltage range, VCC: -0.5 V to 7 V; (2)Input clamp current, IIK (VI < 0 or VI > VCC): ±20 mA; (3)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (4)Continuous output current, IO (VO = 0 to VCC): ±25 mA; (5)Continuous current through VCC or GND: ±50 mA; (6)Package thermal impedance, θJA: D package: 73℃/W, DW package: 57℃/W, N package: 67℃/W, NS package: 64℃/W; (7)Storage temperature range, Tstg: -65℃ to 150℃.
Features
SN74HC148N features: (1)Wide Operating Voltage Range of 2 V to 6 V; (2)Outputs Can Drive Up To 10 LSTTL Loads; (3)Low Power Consumption, 80-μA Max ICC; (4)Typical tpd = 16 ns; (5)±4-mA Output Drive at 5 V; (6)Low Input Current of 1 μA Max; (7)Encode Eight Data Lines to 3-Line Binary (Octal).
