1. Describe

The SN74HC244PWR octal buffer and line driver is designed for enhanced performance and densities of tri-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SNx4HC244 device is organized as two 4-bit buffers and drivers with separate output enable (OE) inputs. When OE is low, the device passes In-phase data from A input to Y output. When OE is high, the output is in a high impedance state.

2. Feature

    1. Wide operating voltage range from 2 V to 6 V

    2. High current output drives up to 15 LSTTL loads

    3. Three-state output to drive bus or buffer memory address register

    4. Low power consumption: ICC, 80µA (max)

    5. Typical tpd = 11 ns

    6. ±6 mA output drive at 5 V

    7. Low input current of 1 µA (max)

    8. On products conforming to MIL-PRF-38535, all parameters are tested unless otherwise noted. 

    9. On all other products, production processing does not necessarily include testing all parameters.

3. Application

    1. Server

    2. LED display

    3. Network switches

    4. Telecom infrastructure

    5. motor driver

    6. I/O expander

4. Pin configuration

5. Pin Description

6. Function description

The SNx4HC244 has a wide operating voltage of 2 V to 6 V. The input accepts voltage levels up to VCC. this device Low power consumption of ICC 80 µA (max). The SNx4HC244 device can drive ±6 mA from a VCC of 5 V.

7. Application Information

The SN74HC244 is a high-drive CMOS device that can be used in applications with multiple bus interface types Where output drive or PCB trace length is an issue.
