Philips Semiconductors

Product specification

32-bit edge-triggered D-type flip-flop with

5 V tolerant inputs/outputs; 3-state

74LVCH32374A

DC CHARACTERISTICS

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

Notes

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.

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