74LVC162373A; 74LVCH162373A
General description
The 74LVC(H)162373A is a 16-bit D-type transparent latch featuring separate D-type inputs for each latch and 3-state outputs for bus oriented applications. One latch enable (pin nLE) input and one output enable (pin nOE) are provided for each octal. Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation, outputs can handle 5 V. These features allow the use of these devices in a mixed 3.3 and 5 V environment.
The 74LVC(H)162373A consists of 2 sections of eight D-type transparent latches with 3-state true outputs. When pin nLE is HIGH, data at the corresponding data inputs (pins nDn) enter the latches. In this condition the latches are transparent, i.e., a latch output will change each time its corresponding data inputs changes.
When pin nLE is LOW the latches store the information that was present at the data inputs a set-up time preceding the HIGH-to-LOW transition of pin nLE. When pin nOE is LOW, the contents of the eight latches are available at the outputs. When pin nOE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the nOE input does not affect the state of the latches.
The 74LVCH162373A bushold data inputs eliminates the need for external pull-up resistors to hold unused inputs.
The 74LVC(H)162373A is designed with 30 Ohm series termination resistors in both high and low output stages to reduce line noise.
Features
