74LV244AT規(guī)格書詳情
1. General description
The 74LV244AT is an 8-bit buffer/line driver with 3-state outputs and TTL inputs. The
device features two output enables (1OE and 2OE). A HIGH on nOE causes the
associated outputs to assume a high-impedance OFF-state.
Designed to operate over a VCC range from 4.5 V to 5.5 V, the inputs are TTL compatible,
which allows the device to be used to translate from 3.3 V to 5 V.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall
times.
This device is fully specified for partial Power-down applications using IOFF.
The IOFF circuitry disables the output, preventing the damaging backflow current through
the device when it is powered down.
