Product Summary

The HD74LS373P is an 8-bit register features totem-pole three-state outputs designed specifically for driving highlycapacitive
or relatively low-impedance loads. The high-impedance third state and increased high-logic-level drive provide this register with the capacity of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components. The HD74LS373P is particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
