Introduction:
The 74LS173 4-bit registers include D-type flip-flops featuring totem-pole 3-state outputs capable of driving highly capacitive or relatively low-impedance loads. The high-impedance third state and increased high-logic-level drive provide these flip-flops with the capability of being connected directly to and driving the bus lines in a bus-organized system without the need for interface or pull-up components. Up to 128 of the 74LS173 outputs can be connected to a common bus and still drive two Series 74LS TTL normalized loads, respectively. Similarly, up to 49 of the SN54173 or SN54LS173A outputs can be connected to a common bus and drive one additional Series 74 or 74LS TTL normalized load, respectively.
Some Core Parameters:
SPECIAL FEATURES :

● for application as Bus Buffer Registers
● Fully Edge-Triggered

The goods are received on time, until I checked, as I will check the feedback. The seller sent on time, everything came safe and sound.
