Description
A pair of SN74LS173AN integrated circuits featuring 4-bit D-type registers with independent clocks and 3-state totem-pole outputs.
These versatile components are ideal for high speed digital systems, allowing direct interfacing with system buses without additional interface or pull-up components.
With gated output control and high impedance state, the SN74LS173 ICs are perfectly suited for use in bus organised microprocessor systems, memory registers, or general-purpose latching and buffering applications.
