Description

The 74LVC138AD is designed as a low voltage, low power, high performance, sigate CMOS device, superior to most advanced CMOS compatible TTL families.

The ten features of the 74LVC138AD. (1)Wide supply voltage range of 1.2V to 3.6V. (2)Its in accordance with JEDEC standard no.8-1A. (3)Inputs accept voltages up to 5.5V. (4)CMOS lower power consumption. (5)Direct interface with TTL levels. (6)Demultiplexing capability. (7)Multiple input enable for easy expansion. (8)Ideal for memory chip select decoding. (9)Active low mutually exclusive outputs. (10)Output drive capability 50ohms transmission lines at 85°C. Those are all the main features.

Some absolute maximum ratings of the 74LVC138AD have been concluded into several points as follow. (1)Its DC supply voltage would be from -0.5V to 6.5V. (2)Its DC input diode current would be -50mA. (3)Its DC input voltage would be from -0.5V to 6.5V. (4)Its DC output diode curent would be +/-50mA. (5)Its DC output voltage output high or low would be from -0.5V to Vcc+0.5V. (6)Its DC input voltage output 3-state would be from -0.5V to 6.5V. (7)Its DC output source or sink current would be +/-50mA. (8)Its DC Vcc or GND current would be +/-100mA. (9)Its storage temperature range of the 74LVC138AD 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 the 74LVC138AD are concluded as follow. (1)Its high level input voltage would be min Vcc at Vcc=1.2V and would be min 2.0V at Vcc=2.0V to 3.6V. (2)Its low level input voltage would be max GND at Vcc=1.2V and would be max 0.8V at Vcc=2.7V to 3.6V. (3)Its input leakage current would be typ 0.1uA and max 5uA. (4)Its quiescent supply current would be typ 0.1uA and max 10uA. (5)Its additional quiescent supply per input pin would be typ 5uA and max 500uA. And so on.
