It contains four independent latches with differential outputs (Q and Q-bar), each with a 1:1 circuit ratio. The part operates from a 4.75V to 5.25V supply and is rated for the commercial temperature range of 0°C to 70°C, making it suitable for indoor PCB-level logic applications such as register storage, data buffering, and control-latch functions in legacy TTL systems. ## 9 ns Propagation Delay — Timing Margin for Slower Buses The 9 ns propagation delay is typical for the 74LS family. In a 5 V TTL system running at a few megahertz, this delay leaves comfortable timing margin for address latching or data-path staging. The output drive capability is 400 µA sourcing and 8 mA sinking, which is enough to drive one or two standard TTL loads but not a long backplane trace without a buffer. ## Active Lifecycle — No Obsolescence Concern The SN74LS75N is listed as Active with ROHS3 compliance. ## Package and Mounting — Through-Hole 16-DIP The 16-DIP package (0.300\" width, 7.62 mm pitch) is a standard through-hole footprint. No special baking or moisture sensitivity handling is required — the part is not moisture-sensitive like fine-pitch SMD packages. Store the tubes in a dry environment, but there is no MSL bake requirement before assembly.","metaTitle":"SN74LS75N Quad D-Type Transparent Latch, 74LS, 9ns, 16-DIP","metaDescription":"SN74LS75N quad bistable latch from TI 74LS family. 4.75V–5.25V supply, 9ns propagation delay, 400µA/8mA output drive.

The 74FCT573APC is not pin-compatible (different pin count and logic function), but it serves a similar latching role in a 5V TTL system.
