General description
The 74LVCH32244A is a high-performance, low-power, low-voltage, Si-gate CMOS
device and superior to most advanced CMOS compatible TTL families. Inputs can be
driven from either 3.3 V or 5.0 V devices. In 3-state operation outputs can handle 5 V.
These features allow the use of these devices as translators in a mixed 3.3 V and 5 V
environment.
The 74LVCH32244A is a 32-bit non-inverting buffer/line driver with 3-state outputs. The
3-state outputs are controlled by eight output enable outputs (1OE to 8OE). A HIGH on pin
nOE causes the outputs to assume a high-impedance OFF-state.
To ensure the high-impedance state during power-up or power-down, pin nOE should be
tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by
the current-sinking capability of the driver.
Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused
or floating data inputs at a valid logic level.
