1. General description
The 74LVC1G79 provides a single positive-edge triggered D-type flip-flop.
Information on the dat a input is transferred to the Q-ou tput on the LOW -to-HIGH transition
of the clock pulse. The D-input must be stab le one set-up time prior to the LOW-to-HIGH
clock transition for predictable operation.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this
device in a mixed 3.3 Vand 5 V environment.
This device is fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the outpu t, preventing the damaging ba ckflow current through the device
when it is powered down.
2. Features and benefits
Wide supply voltage range from 1.65 V to 5.5 V
High noise immunity
Complies with JEDEC standard:
JESD8-7 (1.65 V to 1.95 V)
JESD8-5 (2.3 V to 2.7 V)
JESD8B/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115 -A ex ce ed s 200 V
24 mA output drive (VCC =3.0V)
CMOS low power consumption
Latch-up performance exceeds 250 mA
Direct interface with TTL levels
Inputs accept voltages up to 5 V
Multiple package options
Spe cified from 40 Cto+85C and 40 Cto+125C.
