HD74HC147 10-to-4-line Priority Encoder REJ03D0572-0200 (Previous ADE-205-446) Rev.2.00 Oct 11, 2005 Description The HD74HC147 features priority encoding of the inputs to ensure that only the highest order data line is encoded. Nine input lines are encoded to a four line BCD output. The implied decimal zero condition requires no input condition as zero is encoded when all nine data lines are at a high logic level. All data inputs and outputs are active at the low logic level. Features • • • • • • High Speed Operation: tpd = 14.5 ns typ (CL = 50 pF) High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Ordering Information Part Name HD74HC147P Package Type DILP-16 pin Package Code (Previous Code) PRDP0016AE-B (DP-16FV) Package Abbreviation P — PRSP0016DH-B FP (FP-16DAV) Note: Please consult the sales office for the above package availability.
