FSTD16244
16-Bit Bus Switch with Level Shifting (Preliminary)
General Description
The Fairchild Switch FSTD16244 provides 16-bits of high-
speed CMOS TTL-compatible bus switching. The low On
Resistance of the switch allows inputs to be connected to
outputs 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 a 16-bit switch. There are four
4-bit switches with separate output enable inputs. When
OE is LOW, the switch in ON and Port A is connected to
Port B. When OE is HIGH, the switch OFF and a high
impedance state exists between the A and B Ports.
