HD74LVC244 Datasheet – Octal Buffer, Eight Line Driver

Part Number: HD74LVC244

Function : Octal Buffers / Line Drivers with 3-state Outputs

Package: DIP 20 Pin

Manufacturer: Hitachi Semiconductor

Image and Pinout



The HD74LVC244 has eight line drivers with three state outputs in a 20 pin package. This device is a non inverting buffer and has two active low enables (1- and 2*). Each enable independently controls four buffers. Low voltage and high speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.



1. VCC = 2.0 V to 5.5 V
2. All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
3. Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
4. Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)
5. High output current ±24 mA (@VCC = 3.0 V to 5.5 V)
