74ALVC245
Low Voltage Bidirectional Transceiver with 3.6V
Tolerant Inputs and Outputs
Features
■ 1.65V to 3.6V V_CC supply operation
■ 3.6V tolerant inputs and outputs
■ Power-off high impedance inputs and outputs
■ Supports Live Insertion and Withdrawal⁽¹⁾
■ t_PD:
– 3.4ns max. for 3.0V to 3.6V V_CC
– 3.9ns max. for 2.3V to 2.7V V_CC
– 6ns max. for 1.65V to 1.95V V_CC
■ Uses patented Quiet Series noise/EMI reduction
circuitry
■ Latchup conforms to JEDEC JED78
■ ESD performance:
– Human body model > 2000V
– Machine model > 200V
Note:
1. To ensure the high impedance state during power up
and power down, OE_n should be tied to V_CC through a
pull up resistor. The minimum value of the resistor is
determined by the current sourcing capability of the
driver.
General Description
The ALVC245 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 74ALVC245 is designed for low voltage (1.65V to
3.6V) V_CC applications with I/O compatibility up to 3.6V.
The 74ALVC245 is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining low CMOS power dissipation.
