UNISONIC TECHNOLOGIES CO., LTD U74AHCT157 QUADRUPLE 2-LINE TO 1-LINE DATA SELECTOR/ MULTIPLEXER DESCRIPTION The U74AHCT157 is a quadruple 2-line to 1-line data selector/multiplexer. When G is high, all outputs are low. When G is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The devices provide true data. FEATURES * TTL-Voltage Compatible * Max tPD of 4.1ns from A or B to Y at 5V, CL=15pF * Low Quiescent Current: ICC = 2 μA (MAX) at 5.5V * ±8 mA output driver at 5V CMOS IC ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74AHCT157L-P16-R U74AHCT157G-P16-R U74AHCT157L-P16-T U74AHCT157G-P16-T Package TSSOP-16 TSSOP-16 Packing Tape Reel Tube www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-652.A 1 page U74AHCT157 TEST CIRCUIT AND WAVEFORMS CMOS IC VCC 5V±0.5V Input VIN tR, tF VCC ≤3ns TEST tPLH/tPHL tPLZ/tPZL tPHZ/tPZH S1 Open VLOAD GND VM VCC/2 VLOAD VCC CL 15pF 50pF RL 1kΩ VΔ 0.5V UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 5 of 6 QW-R502-652.A 5 Page
