FSTU32160
General Description
The ON Semiconductor Switch FSTU32160 is a 16−bit to 32−bit
highspeed CMOS TTL−compatible multiplexer/demultiplexer bus
switch. The low on resistance of the switch allows inputs to be
connected to outputs without adding propagation delay or generating
additional ground bounce noise.
The device can be used in applications where two buses need to be
addressed simultaneously. The FSTU32160 is designed so that the A
Port demultiplexes into B1 or B2 or both. The A and B Ports have
“undershoot hardened” circuit protection to support an extended range
to 2.0 V below ground. The integrated Undershoot Hardened Circuit
senses undershoot at the I/O’s, and responds by preventing voltage
differentials from developing and turning on the switch.
Two select (S1, S2) inputs provide switch enable control. When S1,
S2 are HIGH, the device precharges the B Port to a selectable bias
voltage (Bias V) to minimize live insertion noise.
Features
Undershoot hardened to −2 V (A and B Ports)

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. VS is the voltage observed/applied at either the A or B Ports across the switch.
2. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
