Philips Semiconductors
12-bit 1-of-2 multiplexer/demultiplexer
with internal pulldown resistors
Product specification
CBT16292
FEATURES
• 6 Ω switch connection between two ports
• TTL compatible control input levels
• Break-before-make feature
• Internal 500 Ω pulldown resistors to ground
• Latch-up protection exceeds 500 mA per JESD78
• ESD protection exceeds 2000 V HBM per JESD22-A114,
200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
DESCRIPTION
The CBT16292 is a 12-bit 1-of-2 high-speed TTL-compatible
multiplexer/demultiplexer. The low on-state resistance of the switch
of the switch allows connections to be made with minimal
propagation delay.
When the select (S) input is low, port A is connected to port B1 and
RINT is connected to port B2. When S is high, port A is connected to
port B2 and RINT is connected to port B1.
The CBT162292 is characterized for operation from –40°C to +85°C.
