74LVC16373 Philips, 74LVC16373 Datasheet - Page 6

• Manufacturer Part Number: 74LVC16373
• Description: 16-bit D-type transparent latch with 5 Volt tolerant inputs/outputs 3-State
• Manufacturer: Philips

1. All typical values are at V
2. Valid for data inputs of bus hold parts (LVCH16-A) only.
3. For data inputs only, control inputs do not have a bus hold circuit.
4. The specified sustaining current at the data input holds the input below the specified V
5. The specified overdrive current at the data input forces the data input to the opposite logic input state.
6. For bus hold parts, the bus hold circuit is switched off when V
1. All typical values are at V
