FSTD3125
4-Bit Bus Switch with Level Shifting
General Description
The Fairchild Switch FSTD3125 provides four high-speed
CMOS TTL-compatible bus switches. The low On Resis-
tance of the switch allows inputs to be connected to out-
puts without adding propagation delay or generating
additional ground bounce noise. A diode to V
CC
has been
integrated into the circuit to allow for level shifting between
5V inputs and 3.3V outputs.
The device is organized as four 1-bit switches with sepa-
rate OE inputs. When OE is LOW, the switch is ON and
Port A is connected to Port B. When OE is HIGH, the
switch is OPEN and a high-impedance state exists
between the two ports.
