Product speciﬁcation

32-bit transparent D-type latch with

5 V tolerant inputs/outputs; 3-state

74LVCH32373A

DC CHARACTERISTICS

Over recommended operating conditions; voltages are referenced to GND (ground=0V).

Notes

1. All typical values are at VCC = 3.3 V and Tamb =25 °C.

2. For bus hold parts the bus hold circuit is switched off when VI exceeds VCC allowing 5.5 V on the input terminal.

3. Valid for data inputs of bus hold parts (LVCH32-A) only.

4. For data inputs only; control inputs do not have a bus hold circuit.

5. The specified sustaining current at the data input holds the input below the specified VI level.

6. The specified overdrive current at the data input forces the data input to the opposite logic input level.
