OCTAL TRANSPARENT D-TYPE
LATCHES WITH 3-STATE
OUTPUTS
DESCRIPTION
The UTC U74LVC373 is a octal transparent D-type latch with
3-state outputs, and it has 8 channels.
FEATURES
* Operate from 1.65V to 3.6V
* Inputs accept voltages to 5.5V
* Max tpd of 6.8ns @ 3.3V
* Typical VOL<0.8V @ VCC=3.3V, Ta=25°C
* Typical VOH>2.0V @ VCC=3.3V, Ta=25°C
* Support mixed-mode signal operation on all ports (5V input/output
voltage with 3.3V VCC
)
* I off supports partial-power-down mode operation
* Halogen Free

Note: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Voltage range applied to any output in the high-impedance or power-off state.
3. Voltage range applied to any output in the high or low state, and VCC is provided in the recommended
operating conditions table.
