74LVC245ADB

The 74LVC245ADB is a high performance,low power,low voltage Si-gate CMOS device and superior to most advanced CMOS compatible TTL families.Input can be driven from either 3.3V or 5.0v devices.In 3-state operation,outputs can handle 5V.This feature allows the use of these devices as translators in a mixed 3.3V/5V environment.

Features of the 74LVC245ADB are:(1)5 volt tolerant input/outputs,for interfacing with 5 volt logic;(2)supply voltage range of 2.7V to 3.6V;(3)CMOS low power consumption;(4)direct interface with TTL levels;(5)complies with JEDEC standard no.8-1A;(6)high impedance when VCC=0V.

The absolute maximum ratings of the 74LVC245ADB can be summarized as:(1):the symbol is VCC,the parameter is DC supply voltage,the rating is -0.5 to +6.5,the unit is V;(2):the symbol is IIK,the parameter is DC input diode current,the rating is -50,the unit is mA;(3):the symbol is VI,the parameter is DC input voltage,the rating is -0.5 to +6.5,the unit is V;(4):the symbol is IOK,the parameter is DC output diode current,the rating is ±50,the unit is mA;(5):the symbol is VO,the parameter is DC output voltage:output high or low,the rating is -0.5 to VCC+0.5,the unit is V;(6):the symbol is VO,the parameter is DC output voltage:output 3-state,the rating is -0.5 to 6.5,the unit is V;(7):the symbol is IO,the parameter is DC output source or sink current,the rating is ±50,the unit is mA;(8):the symbol is IGND,ICC,the parameter is DC VCC or GND current,the rating is ±100,the unit is mA;(9):the symbol is Tstg,the parameter is storage temperature range,the rating is -65 to +150,the unit is ;(10):the symbol is PTOT,the parameter is power dissipation per package plastic mini-pack(SO),the rating is 500,the unit is mW;(11):the symbol is PTOT,the parameter is power dissipation per package plastic shrink mini-pack(SSOP and TSOP),the rating is 500,the unit is mW.
