PI5C3245 8-Bit Bi-Directional Bus Switch – Key Features & Specifications

1. Core Function:

️· This is a high-speed, low-voltage, bi-directional 8-bit bus switch, controlled by a single enable (BE) input. It's designed to facilitate data transfer between two 8-bit lines.

2. Key Benefits/Characteristics:

️· Low ON-Resistance: Typical RON of 5 ohms, minimizing signal loss.
️· High Bandwidth: Suitable for a wide range of data rates.
️· Low Power Consumption: Designed for low-voltage operation (VCC typically 5V) with low quiescent current.
️· Bi-Directional: Supports data flow in either direction.
️· Enable Control: A single enable pin (BE) controls the switch, allowing easy on/off control of the signal path.
️· Multiple Package Options: Available in QSOP, SOIC and TSSOP packages.

3. Electrical Specifications (Typical Values):

️· Operating Voltage: 5V +/- 5%
️· Quiescent Current (ICC): 0.1 – 3 µA (very low)
️· Propagation Delay (tPLH/tPHL): 0.25 ns (This is extremely fast, contributing minimal delay to the system).
️· Enable Time (tPZH/tPZL): ~1.5 – 6.5ns
️· Switch On Resistance (RON): 5 ohms (typical)

4. Applications:

️· This type of bus switch is useful in a variety of applications including:
- Microprocessor/Memory Address/Data Bus Switching
- Peripheral Address/Data Bus Switching
- Digital Switching Systems

5. Package Options:

️· QSOP (20-pin)
️· SOIC (20-pin)
️· TSSOP (20-pin)
️· Tape and Reel options available with "X" suffix

6. Ordering Information:
