The TC74VHC373FS is a high-speed CMOS Octal D-Type Latch with 3-State Outputs manufactured by Toshiba Semiconductor and Storage. This device features eight D-type latches with individual outputs that can be enabled or disabled using a common output enable (OE) input. The VHC family provides high speed and low power dissipation.

Applications

• Data storage
• Address latching
• Memory interface
• Peripheral device interface
• Digital system control

Features

• 8-bit D-type latch
• High-speed operation: tpd = 5.2 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 μA (max.) at Ta = 25 °C
• Wide operating voltage range: VCC = 2 V to 5.5 V
• 3-State outputs for bus interfacing
• Output enable control
• Available in SOP20 package

Benefits

• Efficient data storage with D-type latches
• Flexible integration with a wide operating voltage range
• Improved system performance due to high-speed operation
• Reduced power consumption, enhancing energy efficiency
• Easy bus interfacing with 3-State outputs
• Convenient output control with the output enable input
• Compact design with the SOP20 package

Additional Details

The TC74VHC373FS consists of eight D-type latches, each with an individual output. When the latch enable (LE) input is high, the output follows the D input. When LE transitions low, the output is latched and remains constant regardless of changes on the D input. The output enable (OE) input controls the state of the outputs; when OE is low, the outputs are enabled, and when OE is high, the outputs are in a high-impedance state. This allows multiple devices to share a bus.
