n HIGH NOISE IMMUNITY:VNIH =VNIL = 28% VCC (MIN.)
n POWER DOWNPROTECTION ON INPUTS
n SYMMETRICAL OUTPUT IMPEDANCE:|IOH| = IOL = 8mA (MIN) at VCC = 4.5V
n BALANCED PROPAGATION DELAYS:tPLH @ tPHL
n OPERATING VOLTAGE RANGE:VCC(OPR) = 2V to 5.5V
n IMPROVED LATCH-UP IMMUNITY
DESCRIPTION
The 74V1G77 is an advanced high-speed CMOS SINGLE D-TYPE LATCH fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is designed to operate from 2V to 5.5V, making this device ideal for portable applications.
The single D-Type latch is controlled by a Latch Enable Input (LE).
While the LE input is held at a high level, the Q output will follow the data input precisely. When the LE input is taken low the Q output is latched precisely at the logic level of D input data.
Power down protection is provided on 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. It’s available in the commercial and extended temperature range.
All inputs and output are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.
