IDT74LVCH162373A

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

The IDT74LVCH162373A 16-bit transparent D-type latch is built using advanced dual metal CMOS technology. This high-speed, low-power latch is ideal for temporary storage of data. The LVCH162373A can be used for implementing memory address latches, I/O ports, and bus drivers. The output enable and latch enable controls are organized to operate each device as two 8-bit latches or one 16-bit latch. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin.

All pins of the IDT74LVCH162373A can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V supply system.

The IDT74LVCH162373A has series resistors in the device output structure which will significantly reduce line noise when used with light loads. The driver has been developed to drive ±12mA at the designated threshold levels.

The IDT74LVCH162373A has "bus-hold" which retains the inputs' last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors.
