SNJ54HC244J

The Texas Instruments SNJ54HC244J is an octal buffer and line driver designed for high-performance bus interfacing. This device features 8 channels, each capable of buffering noninverted data with 3-state outputs. The outputs can drive up to 15 LSTTL loads and are suitable for bus lines or memory address registers.

With a wide operating voltage range from 2V to 6V, the SNJ54HC244J offers flexibility in various applications. It boasts a very high speed with a typical propagation delay of 11ns and low power consumption, drawing a maximum of 80µA supply current. The output drive capability is ±6mA at 5V, and the input current is a low maximum of 1µA.

This component is rated for military operating temperatures ranging from -55°C to 125°C. It is available in multiple package types including CFP, LCCC, and CDIP, with standard package quantities of 20.

The SNJ54HC244J is organized as two independent 4-bit buffers and drivers, each controlled by separate output-enable (OE) inputs. When OE is low, data passes from the A inputs to the Y outputs. When OE is high, the outputs enter a high-impedance state, making it ideal for bus-oriented systems.
