74LVC1G79

Single D-type flip-flop; positive-edge trigger

The 74LVC1G79 is a single positive-edge triggered D-type flip-flop. Data at the D-input that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition will be stored in the flip-flop and appear at the Q output. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device is fully specified for partial power down applications using I_OFF. The I_OFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

Features and benefits

Wide supply voltage range from 1.65 V to 5.5 V
Overvoltage tolerant inputs to 5.5 V
High noise immunity
CMOS low power dissipation
±24 mA output drive (V_CC = 3.0 V)
Direct interface with TTL levels
Latch-up performance exceeds 250 mA
I_OFF circuitry provides partial Power-down mode operation
Complies with JEDEC standard:
- JESD8-7 (1.65 V to 1.95 V)
- JESD8-5 (2.3 V to 2.7 V)
- JESD8C (2.7 V to 3.6 V)
- JESD36 (4.5 V to 5.5 V)
ESD protection:

- CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C and -40 °C to +125 °C.
