The maximum clock frequency of the SN74LS373DWR is 20 MHz.
To ensure that the outputs are in a high-impedance state during power-up, connect the OE (output enable) pin to VCC or use an external pull-up resistor to VCC.
The SN74LS373DWR can sink up to 24 mA and source up to -15 mA per output.
The SN74LS373DWR is a 5V device, so ensure that the interface voltage levels are compatible. Use level shifters or voltage translators if necessary.
The DIR pin determines the direction of data flow. When DIR is high, the device operates in the latch mode, and when DIR is low, the device operates in the buffer mode.
