Description

The 74ALVCH2245WM includes eight non-inverting bidirectional buffers with 3-STATE outputs and is aimed for bus oriented applications. The T/R input decides the direction of data flow.  The 74ALVCH2245WM data inputs contain active bushold circuitry,removing the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level.

Features of 74ALVCH2245WM are:(1)1.65V to 3.6V VCC supply operation; (2)3.6V tolerant control inputs; (3)bushold on data inputs eliminates the need for externalpull-up/pull-down resistors; (4)26 series resistors in B Port outputs; (5)tPD (A to B):4.9 ns max for 3.0V to 3.6V VCC,6.1 ns max for 2.3V to 2.7V VCC,9.8 ns max for 1.65V to 1.95V VCC; (6)uses patented Quiet Series. noise/EMI reductioncircuitry; (7)latchup conforms to JEDEC JED78; (8)ESD performan ce:human body model > 2000V,machine model > 200V.

The absolute maximum ratings and DC electrical characteristics of the 74ALVCH2245WM can be summarized as:(1): supply voltage is-0.5V to +4.6V;(2):DC input voltage is-0.5V to 4.6V;(3):output voltage is-0.5V to VCC +0.5V;(4):DC input diode current is-50mA when VI is less than 0V;(5):DC output diode current is-50mA when VO is less than 0V;(6):DC output source/sink current is±50 mA;(7):DC VCC or GND current of the 74ALVCH2245WM is±100 mA per supply Pin;(8):storage tempe rature ranges from -65°C to +150°C.DC electrical characteristics:(1):input leakage current is±5.0uA max when VI is between 0V and3.6V;(2):low level output voltage A output is 0.2V max when IOL is 100uA;(3):high level output voltage A output is 1.2V max when IOH is-4mA.
