The PI74FCT843TQA is a 9-bit bus interface D-type latch from Pericom Semiconductor. This device is designed for high-speed bus interface applications requiring temporary storage of data. The 3-state outputs make it suitable for use in bus-oriented systems where multiple devices share a common data path.

Applications

• High-speed bus systems
• Data buffering
• Address latching
• Memory interface
• Microprocessor systems

Features

• High-speed operation: tpd = 4.5 ns (typical)
• Low power consumption
• TTL compatible inputs
• 3-state outputs for bus interface
• Output drive capability: 24mA
• Available in QSOP package

Benefits

• Improved system performance due to fast propagation delays
• Reduced power consumption, contributing to energy efficiency
• Easy integration with TTL logic circuits
• Direct connection to bus lines, simplifying design
• High output drive for reliable signal transmission
• Compact QSOP package for space-constrained applications

Technical Specifications

The PI74FCT843TQA operates with a supply voltage range of 4.75V to 5.25V. It is TTL compatible, ensuring easy integration with other logic devices. The operating temperature range is -40°C to +85°C. The output enable (OE) input controls the 3-state outputs. When OE is high, the outputs are disabled and enter a high-impedance state. The latch enable (LE) input controls when the data is latched. When LE is high, the outputs follow the data inputs. When LE is low, the data is latched, and the outputs remain stable. The device comes in a QSOP (Quarter Size Outline Package). It complies with RoHS standards for environmental safety.
