Product Summary

The fst3125mtcx is a 4-Bit Bus Switch. The low on resistance of the fst3125mtcx allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The fst3125mtcx is organized as four one1-bit switches with separate /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.

Parametrics

fst3125mtcx absolute maximum ratings: (1)VCC Supply Voltage: -0.5 to 7.0 V; (2)VS DC Switch Voltage: -0.5 to 7.0 V; (3)VIN DC Input Voltage: -0.5 to 7.0 V; (4)IIK DC Input Current: 50 mA; (5)IOUT DC Output Sink Current: 128 mA; (6)ICC / IGND DC VCC / GND Current: 100 mA; (7)TSTG Storage Temperature Range: -65 to +150 °C.

Features

fst3125mtcx features: (1)4Ω Switch Connection between Two Ports; (2)Minimal Propagation Delay through the Switch; (3)Low ICC; (4)Zero Bounce in Flow-through Mode; (5)Control Inputs Compatible with TTL Level.
