POWER DOWN PROTECTION ON INPUTS
DESCRIPTION
The 74LVX74 is a low voltage CMOS DUAL
D-TYPE FLIP-FLOP WITH PRESET AND CLEAR
NON INVERTING fabricated with sub-micron
silicon gate and double-layer metal wiring C2MOS
technology. It is ideal for low power, battery
operated and low noise 3.3V applications.
A signal on the D INPUT is transferred to the Q
OUTPUT during the positive going transition of the
clock pulse. CLR and PR are independent of the
clock and accomplished by a low setting on the
appropriate input.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage.
This device can be used to interface 5V to 3V
system. It combines high speed performance with
the true CMOS low power consumption. All inputs
and outputs are equipped with protection circuits
against static discharge, giving them 2KV ESD
immunity and transient excess voltage.
