| 16-BIT 2:1 MUX/DEMUX SWITCH Integrated Device Technology, Inc. IDT74FST163233 ADVANCE INFORMATION FEATURES: * Bus switches provide zero delay paths * Extended commercial range of -40C to +85C * Low switch on-resistance: FST163xxx - 7 * TTL-compatible input and output levels * ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) * Available in SSOP, TSSOP and TVSOP DESCRIPTION: The FST163233 belongs to IDT's family of Bus switches. Bus switch devices perform the function of connecting or isolating two ports without providing any inherent current sink or source capability. Thus they generate little or no noise of their own while providing a low resistance path for an external driver. These devices connect input and output ports through an n-channel FET. When the gate-to-source junction of this FET is adequately forward-biased the device conducts and the resistance between input and output ports is small. Without adequate bias on the gate-to-source junction of the FET, the FET is turned off, therefore with no VCC applied, the device has hot insertion capability. The low on-resistance and simplicity of the connection between input and output ports reduces the delay in this path to close to zero. The FST163233 provides three 16-bit TTL-compatible ports that support 2:1 multiplexing. The SEL0,1 and TEST0,1 pins provide switch enable and mux select control as shown below. The A port can be connected to port 1B or port 2B or both ports 1B and 2B.

See test circuit and waveforms. 2. Minimum limits guaranteed but not tested. 3. This parameter is guaranteed by design but not tested. 4. The bus switch contributes no propagation delay other than the RC delay of the on resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 2.5ns for 50pF load. Since this time is constant and much smaller than the rise/fall times of typical driving signals, it adds very little propagation delay to the system. Propagation delay on the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 5. Measured at switch turn off, load = 50 pF in parallel with 10 M scope probe, VIN = 0.0 volts. 6. Measured at switch turn off through bus multiplexer, (e.g.- A to 1B = >A to 2B), load = 50 pF in parallel with 10 M scope probe, VIN at A = 0.0 volts. Charge injection is reduced because the injection from the turn off of the A to 1B switch is compensated by the turn on of the A to 2B switch. 7. Characterized parameter.
