XD74LS75 – Quad Bistable Transparent Latch – Xinluda

The Xinluda XD74LS75 is a 4-bit quad bistable transparent latch (74LS75-type) with complementary Q and Q outputs, built on low-power Schottky TTL technology for temporary binary data storage.

The Xinluda XD74LS75 is a quad bistable transparent latch, the manufacturer’s branded equivalent of the industry-standard 74LS75 low-power Schottky TTL logic device. It contains four independent latches, each providing both a true (Q) and complementary (Q) output, making it ideal for temporary storage of binary information between processing units and input/output or indicator stages.

Latches are arranged in two pairs, each pair sharing an active-high enable (control) input. When the enable is high, each Q output transparently follows its data (D) input; when the enable goes low, the data present at that moment is retained at the output. This transparent-latch behavior makes the XD74LS75 a versatile building block for data buffering, register, and display-driver applications.

Key Features

• 4-bit quad bistable transparent latch (74LS75 function)
• Complementary Q and Q outputs on each of the four latches
• Low-power Schottky (LS) bipolar TTL technology
• Recommended supply voltage range of 4.75 V to 5.25 V (5 V nominal)
• Two enable (control) inputs, each shared by a pair of latches
• Maximum low-level output sink current of 8 mA (I_OL)
• Commercial operating temperature range of 0°C to +70°C
• Available in 16-pin DIP and SOP packages

Applications

• Temporary storage / data buffering between logic blocks
• Bus-oriented systems and register banks
• Display and indicator latching
• Legacy and retro computing / arcade and pinball board repair
• Industrial control and instrumentation logic
