74ALVCH245MTCX 数据手册 ( 数据表 ) - Fairchild Semiconductor
Fairchild Semiconductor
General Description
The ALVCH245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The T/R input determines the direction of data flow. The OE input disables both the A and B Ports by placing them in a high impedance state. The ALVCH245 data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level.
FEATUREs
■ 1.65V to 3.6V VCC supply operation
■ Bushold on data inputs eliminates the need for external pull-up/pull-down resistors
■ tPD
3.6 ns max for 3.0V to 3.6V VCC
4.2 ns max for 2.3V to 2.7V VCC
6 ns max for 1.65V to 1.95V VCC
■ Uses patented Quiet Series noise/EMI reduction circuitry
■ Latchup conforms to JEDEC JED78
■ ESD performance:
Human body model > 2000V
Machine model > 200V
