Description

The 74LVC646AD is a high performance,low-power,low-voltage Si-gate CMOS device,suprior  to most advanced CMOS compatible TTL families.Inputs 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 74LVC646AD are:(1)wide supply voltage range of 1.2V to 3.6V;(2)in accordance with JEDEC standard no.8-1A;(3)CMOS low power consumption;(4)direct interface with TTL levels;(5)5 volt tolerant inputs/outputs,for interfacing with 5 volt logic;(6)flow-through pin-out architecture.

The absolute maximum ratings of the 74LVC646AD 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 output diode current,the rating is ±50,the unit is mA;(5):the symbol is VI/O,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 VI/O,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 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 of the 74LVC646AD 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 power dissipation per package plastic mini-pack(SO),the rating is 500,the unit is mW;(11):the symbol is PTOT,the parameter power dissipation per package plastic shrink mini-pack(SSOP and TSSOP),the rating is 500,the unit is mW.
