74ls173 Dip IC


1 in stock.


The 74LS173 IC is a high-speed 4-Bit Register featuring 3-state outputs for use in bus-organized systems. The clock is fully edge-triggered allowing either a load from the D inputs or a hold (retain register contents) depending on the state of the Input Enable Lines (IE1, IE2). The 74LS173 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL components. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. The IC 74LS173 is smaller in size and it has a much faster speed which makes it reliable in every kind of device.
