The TC40H373P is an 8-bit transparent latch with three-state outputs manufactured by Toshiba Semiconductor and Storage. This device is ideal for temporary data storage in applications where data needs to be held and then outputted with high impedance when not in use. It is commonly used in memory systems, I/O interfaces, and data bus buffering.

Applications:

• Memory Address Latches
• I/O Port Buffering
• Data Bus Buffering
• Microprocessor Systems
• Industrial Control Systems

Features:

• 8-Bit Transparent Latch
• Three-State Outputs
• High-Speed Operation
• TTL Compatible Inputs and Outputs
• Wide Operating Voltage Range
• DIP Package

Benefits:

• Temporary Data Storage: Efficiently holds 8 bits of data, allowing for temporary storage before being passed on to other parts of the system.
• High-Impedance Outputs: Three-state outputs enable multiple devices to share a common bus without contention, enhancing system flexibility.
• Fast Data Transfer: High-speed operation ensures quick data transfer, minimizing delays in data processing.
• Simple Integration: TTL compatible inputs and outputs simplify interfacing with other digital logic components and microcontrollers.
• Versatile Applications: Suitable for a wide range of applications requiring temporary data storage and bus management.

Additional Details:

The TC40H373P consists of eight transparent latches, each capable of storing one bit of data. When the enable (LE) input is high, the Q outputs follow the D inputs. When the LE input is low, the data present at the D inputs is latched and held at the Q outputs. The output enable (OE) input controls the three-state outputs; when OE is low, the outputs are enabled, and when OE is high, the outputs are in a high-impedance state. The device operates over a wide voltage range, typically from 2V to 6V. Housed in a standard Dual In-line Package (DIP), the TC40H373P is easy to prototype and integrate into existing circuit designs. Its three-state outputs and transparent latch functionality make it a valuable component for digital systems needing temporary data storage and bus management.
