74LVCH245A PHILIPS [NXP Semiconductors], 74LVCH245A Datasheet - Page 8

• Manufacturer Part Number: 74LVCH245A
• Description: Octal bus transceiver with direction pin with 5 V tolerant input/outputs (3-state)
• Manufacturer: PHILIPS [NXP Semiconductors]

Philips Semiconductors
Notes
1. All typical values are measured at V
2. For bus-hold parts, the bus-hold circuit is switched off when V
3. For I/O ports the parameter I
4. Valid for data inputs of bus-hold parts (74LVCH245A) only.
5. For data inputs only, control inputs do not have a bus-hold circuit.
6. The specified sustaining current at the data input holds the input below the specified V
7. The specified overdrive current at the data input forces the data input to the opposite logic input state.
