The SN74LVT244BDWR is a low-voltage, low inhibition, non-inverting octal buffer and line driver designed for low-power and applications requiring signal translation. With the device having eight non-inverting buffers, it can be used to level shift and/or drive signals to meet various logic level requirements.

The SN74LVT244BDWR belongs to the Logic - Buffers, Drivers, Receivers, Transceivers category. This octal buffer and line driver is designed to enhance system performance and reduce power consumption in a variety of applications.

The octal buffer has two input selections per buffer: active-low and active-high, meaning it can support both direct logic and complementary logic. Its inputs can accept signals down to 1.2 volts with no latch-up.The high input inhibition allows the user to tie all of the active-low inputs together or all of the active-high inputs together, and still achieve an active output.

The high output totem-pole drives up to ten LS or fifteen LSTTL loads, and the outputs are initially low, reducing the need for pull-up resistors. The device is designed to operate with Vcc power supply voltages ranging from 1.65 to 3.6 volts. The SN74LVT244BDWR is rated for a minimum operating temperature of -40 °C and a maximum operating temperature of +85 °C.

The SN74LVT244BDWR also feature bus hold circuitry that prevents bus mismatch when data signals are changing; this ensures that the devices valid output state is maintained during a transition. In addition to level shifting, this device also allows fan-out of up to 20 and can be used for low-power logic designated applications.

The SN74LVT244BDWR has a typical propagation delay of 6 ns at 1.8 volts and 8 ns at 3.3 volts, and a maximum propagation delay of 20 ns. With its multiple outputs, this device is ideal for switching, transceiving, and level shifting applications. It is packaged in a 28-pin TSSOP (300 mils) or 28-pin SOIC/PDIP/SOJ package, and is available from several popular manufacturers.
