Overview
The FST16211 is a 24-bit high-speed CMOS TTL-compatible bus switch. It provides two independent 12-bit switches controlled by OE1 and OE2 inputs. The device features low on-resistance, minimal propagation delay, and low quiescent current. Operating voltage ranges from 4.0V to 5.5V with an operating temperature of -40°C to +85°C. Available in BGA54A, MS56A, and MTD56 packages.
Feature Summary
- Provides 24 bits of high-speed CMOS bus switching with TTL-compatible control inputs
- Features low on-resistance for minimal propagation delay and reduced ground bounce noise
- Offers zero bounce operation in flow-through mode with low quiescent supply current
Applications
- High-speed data bus interconnects
- Memory module signal routing
- Peripheral interface expansion
Procurement Notes
Verify the specific package variant required (BGA54A, MS56A, or MTD56) as the base model number covers multiple physical forms. Confirm ordering suffixes for tape and reel availability if needed. Ensure compliance with RoHS standards and check for updated part numbers due to Fairchild integration into ON Semiconductor.
Selection Notes
Select based on required I/O count and package constraints. The device supports dual 12-bit configurations. Verify input voltage levels match system requirements. Consider thermal performance within the specified operating range. Check pinout compatibility for existing PCB layouts when choosing between SSOP, TSSOP, or FBGA options.
Part Context
This component belongs to the FST series of bus switches, designed for high-speed digital signal routing. It replaces older logic families by offering lower power consumption and faster switching speeds. The product line integrates proven switch technology for reliable data transmission in complex digital systems.

FAQ
How are the two ports controlled?
Port 1 is enabled when OE1 is LOW, connecting Port 1A to 1B. Port 2 is enabled when OE2 is LOW. High impedance exists when respective enable pins are HIGH.
What is the maximum operating voltage?
The recommended operating supply voltage (VCC) ranges from 4.0V to 5.5V.
