SN54LVC157AD

The SN54LVC157AD is designed as a quadruple 2-line to 1-line data selectors/multiplexers for 1.65V to 3.6V Vcc operation. SN54LVC157AD features a common strobe input. when it is high, all outputs are low. When it is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. This device provides true data.

SN54LVC157AD has eight features. (1)Operate from 1.65V to 3.6V. (2)Specified from -40°C to 85°C, -40°C to 125°C and -55°C to 125°C. (3)Inputs accept voltages to 5.5V. (4)Max tPD of 5.2ns at 3.3V. (5)Typical Volp(output ground bounce)<0.8V at Vcc=3.3V. (6)Typical Vohv (output Voh undershoot)>2V at Vcc=3.3V. (7)Latch-up performance exceeds 250mA per JESD 17. (8)ESD protection exceeds JESD 22 2000V human body model, 200V machine model and 1000V charged
device model. Those are all the main features.

Some absolute maximum ratings of SN54LVC157AD 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 73°C/W. (9)Its storage temperature range would be from -65°C to 150°C. (10)Its power dissipation would be 500mW. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SN54LVC157AD are concluded as follow. (1)Its output voltage high would be min Vcc-0.2V at Vcc=2.7V to 3.6V and would be min 2.2V at Vcc=2.7V. (2)Its output voltage low would be max 0.2V at Vcc=2.7V to 3.6V and would be max 0.4V at Vcc=2.7V. (3)Its input leakage current would be max +/-5uA. And so on.
