Description

The SN74LVC157AD is designed as a quadruple 2-line to 1-line data selector/multipleser for 1.65V to 3.6V Vcc operation. It features a common strobe input. When the strobe is high, all outputs are low. When the strobe is low, 1 4-bit word is selected from one of two sources and is routed to the four outputs. This device provides true data.

SN74LVC157AD has seven features. (1)EPIC (enhanced performance implanted CMOS) submicron process. (2)Typical Volp (output ground bounce)<0.8V at Vcc=3.3V. (3)Typical Vohv (output Voh undershoot)>2V at Vcc=3.3V. (4)Inputs accept voltages to 5.5V. (5)ESD protection exceeds 2000V per MIL-STD-882, method 3015; exceeds 200V using machine model (C=200pF, R=0). (6)Latch-up performance exceeds 250mA perJESD 17. (7)Package options is plastic small-outline. Those are all the main features.

Some absolute maximum ratings of SN74LVC157AD have been concluded into several points as follow. (1)Its supply voltage range would be from -0.5V to 6.5V. (2)Its input voltage range would be from -0.5v to 6.5V. (3)Its output voltage range would be from -0.5v to Vcc+0.5V. (4)Its input clamp current would be -50mA. (5)Its output clamp current would be -50mA. (6)Its continuous output current would be +/-50mA. (7)Its continuous current through Vcc or GND would be +/-100mA. (8)Its package thermal impedance would be 113°C/W. (9)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SN74LVC157AD are concluded as follow. (1)Its output high voltage would be min Vcc-0.2V at Vcc=1.65V to 3.6V and Ioh=-100uA and would be min 1.2V at Vcc=1.65V and Ioh=-4mA and would be min 1.7V at Vcc=2.3V and Ioh=-8mA. (2)Its output voltage low would be max 0.2V at Vcc=1.65V to 3.6V, Ioh=100uA and would be max 0.45V at Vcc=1.65V, Ioh=4mA and would be max 0.7V at Vcc=2.3V, Iol=8mA. And so on.
