Description

The 74LVC544AD is a high-performance,low-power, low-voltage,Si-gate CMOS device,superior to most advanced CMOS compatible TTL families.The 74LVC4245AD is an octal dual registered inverting transceiver containing two sets of D-type latches for temporary storage of data flow in either directions.

Features of the 74LVC544AD are:(1)5v tolerant inputs/outputs,for interfacing with 5-volt logic;(2)wide supply voltage range of 1.2V to 3.6V;(3)in accordance with JEDEC standard no.8-1A;(4)CMOOS low power consumption;(5)direct interface with TTL levels;(6)combines 74LVC640 and 74LVC533 type functions in one chip;(7)back-to-back registers for storage;(8)separate controis for data flow in each direction;(9)3-state non-inverting outputs for bus oriented appllcations;(10)octal transcelver with D-type latch.

The absolute maximum ratings of the 74LVC544AD can be summarized as:(1):the symbol is VCC,the parameter is 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 VI/O,the parameter is DC output voltage:output high or low state,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 source or sink current of the 74LVC544AD,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 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.
