Philips Semiconductors Product specification
3.3 V 32-bit edge-triggered D-type flip-flop;
3-state
74LVT32374
DC CHARACTERISTICS
Over recommended operating conditions; voltages are referenced to GND (ground=0V).
Notes
1. All typical values are measured at V
CC
= 3.3 V and T
amb
=25°C.
2. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.
3. Unused pins at V
CC
or GND.
4. This is the bus hold overdrive current required to force the input to the opposite logic state.
5. This parameter is valid for any V
CC
between 0 V and 1.2 V with a transition time of up to 10 ms. From V
CC
= 1.2 V
to V
CC
= 3.3 V ± 0.3 V a transition time of 100 µs is permitted. This parameter is valid for T
amb
=25°C only.
6. I
CCZ
is measured with outputs pulled to V
CC
or GND.
7. This is the increase in supply current for each input at the specified voltage level other than V
CC
or GND.
