The TC74VCX373FK(EL) is an 8-bit transparent latch manufactured by Toshiba Semiconductor and Storage. It is designed for high-speed, low-voltage operation, making it suitable for applications where data needs to be temporarily stored and passed through with minimal delay. The (EL) suffix typically indicates specific packaging or handling requirements for automated assembly.

Applications:

• Data buffering
• Address latching
• I/O port expansion
• Microprocessor interfacing
• Memory systems

Features:

• Low-voltage operation (1.65V to 3.6V)
• High-speed propagation delay
• 8-bit transparent latch
• 3-state outputs
• Output enable (OE) control
• Low power consumption
• Surface mount packaging (typically SSOP or similar)

Benefits:

• Fast data transfer
• Flexible bus interfacing with 3-state outputs
• Reduced loading on the data bus
• Power savings in low-voltage systems
• Easy integration into digital systems

Additional Details:

The TC74VCX373FK(EL) is an 8-bit transparent latch, meaning that when the latch enable (LE) input is high, the outputs follow the inputs. When the LE input transitions low, the data present at the inputs is latched and held until the LE input goes high again. The 3-state outputs allow the device to be connected to a shared bus without causing contention. The output enable (OE) input controls whether the outputs are enabled or disabled. When OE is low, the outputs are enabled; when OE is high, the outputs are in a high-impedance state. The device is designed to be compatible with a wide range of logic families, including TTL and CMOS. It typically comes in a small surface-mount package, such as SSOP (Shrink Small Outline Package), making it suitable for high-density board layouts. The TC74VCX373FK(EL) is also designed to withstand electrostatic discharge (ESD) events, enhancing its reliability. The (EL) designation indicates enhanced lead finish, or packaging for easier pick and place during automated PCB assembly.

The TC74VCX373FK(EL) is commonly used in data buffering, address latching, and microprocessor interfacing applications. Its low-voltage operation makes it suitable for battery-powered devices and other low-power applications. The high-speed performance ensures that the latch does not introduce significant delays into the signal path. The Toshiba TC74VCX series is known for its quality and performance, making the TC74VCX373FK(EL) a popular choice for digital designers. The device meets industry standards for electromagnetic compatibility (EMC).
