Description
The IH5140 Family of CMOS switches utilizes Harris’ latch free junction isolated processing to build the fastest switches currently available. These switches can be toggled at a rate of greater than 1MHz with fast tON times (80ns typical) and faster tOFF times (50ns typical), guaranteeing break before make switching. This family of switches combines the speed of the hybrid FET DG180 family with the reliability and low power consumption of a monolithic CMOS construction.
Very low quiescent power is dissipated in either the ON or the OFF state of the switch. Maximum power supply current is 10µA (at 25oC) from any supply and typical quiescent currents are in the 10nA which makes these devices ideal for portable equipment and military applications.
The IH5140 Family is completely compatible with TTL (5V) logic, TTL open collector logic and CMOS logic. It is pin compatible with Harris’ IH5040 family and part of the DG180/DG190 family as shown in the switching state diagrams.
