Each latch presents a differential output pair — true and complement — which is useful for driving balanced lines or feeding a downstream differential receiver without an extra inverter. Propagation delay is 9ns typical, fast enough for moderate-speed address/data latching in 5V control systems running below 50 MHz. The supply range is 4.75V to 5.25V, matching standard 5V TTL rails. Output drive capability is 400µA sourcing and 8mA sinking — typical for 74LS. Fan-out to standard TTL loads is adequate, but driving a heavily loaded bus or long trace may require a buffer. ## Package, temperature grade, and board-fit considerations Housed in a 16-SOIC (0.154-inch body width, 3.90 mm) surface-mount package. The pin pitch is compatible with standard SOIC land patterns and reflow profiles. No exposed pad — thermal management is through the leadframe and board copper. Rated for commercial temperature range: 0°C to 70°C. This limits the part to controlled indoor environments — not suitable for industrial, automotive, or outdoor deployment without additional thermal qualification. ## Lifecycle and supply posture ROHS3 compliant.","metaTitle":"SN74LS75D – TI 74LS Quad D-Type Transparent Latch, 16-SOIC","metaDescription":"Texas Instruments SN74LS75D: 74LS quad D-type transparent latch with differential outputs, 9ns propagation delay, 4.75V–5.25V supply, 0°C–70°C. 16-SOIC.","metaKeywords":null},"attributes":{"series":"74LS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Series":"74LS","Circuit":"1:1","Package":"Tube","Logic Type":"D-Type Transparent Latch","Output Type":"Differential","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Independent Circuits":"4","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"16-SOIC","Delay Time - Propagation":"9ns","Current - Output High, Low":"400µA, 8mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.65","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.65000","currency":"USD"},{"qty":10,"price":"$2.38200","currency":"USD"},{"qty":25,"price":"$2.24720","currency":"USD"},{"qty":100,"price":"$1.91460","currency":"USD"},{"qty":250,"price":"$1.79776","currency":"USD"},{"qty":500,"price":"$1.57304","currency":"USD"},{"qty":1000,"price":"$1.30338","currency":"USD"},{"qty":2500,"price":"$1.27200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c4d1c69b6972de3b913aa6073a3876d8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional equivalent to SN74LS75D?","answer":"A functional alternative is the 74FCT573APC from the 74FCT family. That part is an octal D-type transparent latch (8-bit vs quad), with tri-state non-inverted outputs, 8.5ns propagation delay, and through-hole DIP package. It is not a pin-for-pin replacement — the SN74LS75D has differential outputs and a 16-SOIC footprint.
