SN74ACT244PWR 8-ch, 4.5-V to 5.5-V buffers with TTL-compatible CMOS inputs and 3-state outputs

short description:

This SN74ACT244PWR buffer and line driver is used to amplify an analog or digital signal by driving the input to the transmission line. With a 3-state output, this is power management at its best. This line driver has a minimum operating temperature of -40 °C and a maximum of 85 °C. This product will be shipped in tape and reel packaging to allow for quick mounting and safe delivery. This non-inverting device has a typical operating supply voltage of 5 V. Its minimum operating supply voltage of 4.5 V, while its maximum is 5.5 V. It has 8 channels per chip.

Detailed Introduction

These SNx4ACT244 octal buffers and drivers are designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SNx4ACT244 devices are organized as two 4-bit buffers and drivers with separate output-enable (OE) inputs. When OE is low, the device passes non inverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high impedance state.
