74lvc244abq NXP Semiconductors, 74lvc244abq Datasheet - Page 8

• Manufacturer Part Number: 74lvc244abq
• Description: Octal Buffer/line Driver With 5 V Tolerant Inputs/outputs 3-state
• Manufacturer: NXP Semiconductors

Philips Semiconductors
Notes
1. All typical values are measured at V
2. For bushold parts, the bushold circuit is switched off when V
3. Valid for data inputs of bushold parts (74LVCH244A) only. For data inputs only, control inputs do not have a bushold
4. The specified sustaining current at the data inputs do not have a bushold circuit.
5. The specified overdrive current at the data input forces the data input to the opposite logic input state.
