Sunnyvale, Calif.Maxim Integrated Products has introduced the DS3690 3.3V, 26-channel, bidirectional CMOS transmission gate.
Providing 26 independent channels that can be used for input, output, or I/O signal applications, the DS3690 eliminates the signal-isolation problems associated with standard bus transceivers. According to Maxim, the DS3690 saves both cost and board space in applications such as point-of-sale terminals, PIN pads, and cryptographic processors in which a downstream component must be isolated from an address or data bus in a timely manner.
Each of the DS3690's 26 independent channels consists of two pins. Because each channel is bidirectional, either of its pins can be used as the input pin for a unidirectional signal. A change in logic state on any one side of the channel is directly reflected on the opposite side of that channel.
Packaged in a lead-free, 5mm x 11mm x 0.8 mm, 56-pin TQFN, the DS3690 is fully specified over the -55°C to +85°C extended temperature range.
Pricing: Starts at $3.50 (1000-up, FOB USA).
