74LVC1G79
Single D-type flip-flop; positive-edge trigger
Rev. 07 — 29 August 2007
Product data sheet
1. General description
The 74LVC1G79 provides a single positive-edge triggered D-type flip-flop.
Information on the data input is transferred to the Q-output on the LOW-to-HIGH transition
of the clock pulse. The D-input must be stable 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 V and 5 V environment.
This device is fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the output, preventing the damaging backflow current through the device
when it is powered down.
2. Features
■ 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)
■ ±24 mA output drive (VCC = 3.0 V)
■ 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
■ ESD protection:
◆ HBM JESD22-A114E exceeds 2000 V
◆ MM JESD22-A115-A exceeds 200 V
■ Specified from −40 °C to +125 °C

[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] When VCC = 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
[3] For TSSOP5 and SC-74A packages: above 87.5 °C the value of Ptot derates linearly with 4.0 mW/K.
For XSON6 packages: above 45 °C the value of Ptot derates linearly with 2.4 mW/K.
