These 8-bit latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.The eight latches of the 74F373N are transparent D-type latches. While the latch-enable (LE) input is high, the Q outputs will follow the data (D) inputs. When the latch enable is taken low, the Q outputs are latched at the logic levels set up at the D inputs.A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without need for interface or pullup components.The output-enable (OE) input does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. The 74F373N is characterized for operation from 0?C to 70?C.Features:Eight Latches in a Single Package3-State Bus-Driving True OutputsFull Parallel Access for LoadingBuffered Control Inputs20 pin DIP.
