Bus Transceiver eliminates signal-isolation problems.January 28, 2008 -
Designed for transparent digital signal transfer and fast-gated bus isolation, Model DS3690 is 3.3 V, 3-state transmission gate that provides 26 independent channels which can be used for input, output, or I/O signal applications. Packaged in lead-free, 5 x 11 x 0.8 mm, 56-pin TQFN, it is fully specified over -55 to +85°C extended temperature range. Unit suits applications such as point-of-sale terminals, PIN pads, cryptographic processors, and lottery terminals.

Industry's First 26-Channel, Universal, Bidirectional Bus Transceiver Eliminates Signal-Isolation Problems
o The DS3690 is a 3.3 V, 26-channel, three-state transmission gate designed for transparent digital signal transfer and fast-gated bus isolation.
o This device eliminates the signal-isolation problems associated with standard bus transceivers.
o To enable these benefits, the DS3690 provides 26 independent channels that can be used for input, output, or I/O signal applications, thereby saving cost and board space over standard bus transceivers.
o The DS3690 is ideal for applications such as point-of-sale terminals, PIN pads, cryptographic processors, and lottery terminals in which a downstream component must be isolated from an address or data bus in a timely manner.
SUNNYVALE, CA-January 9, 2008-Maxim Integrated Products (Pink Sheets: MXIM) introduces the DS3690 3.3 V, 26-channel, bidirectional CMOS transmission gate. Providing 26 independent channels that can be used for input, output, or I/O signal applications, this device eliminates the signal-isolation problems associated with standard bus transceivers. The DS3690, thus, 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, 5 mm x 11 mm 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).
