INTEGRATED CIRCUITS CBT3257 Quad 1-of-2 multiplexer/demultiplexer Product data Supersedes data of 27 Sep 2002 Philips Semiconductors 2002 Dec 13 Philips Semiconductors Product data Quad 1-of-2 multiplexer/demultiplexer FEATURES CBT3257 PIN CONFIGURATION • 5 Ω switch connection between two ports • TTL-compatible input levels • Minimal propagation delay through the switch • 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 CBT3257 is a quad 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

All typical values are at VCC = 5 V, Tamb = 25 °C. 2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND 3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is determined by the lowest voltage of the two (A or B) terminals. 2002 Dec 13 4 Philips Semiconductors Product data Quad 1-of-2 multiplexer/demultiplexer CBT3257 AC CHARACTERISTICS Tamb = -40 to +85 °C; CL = 50 pF LIMITS SYMBOL PARAMETER FROM (INPUT) TO (OUTPUT) VCC = +5.0 V ±0.5 V MIN MAX UNIT tpd Propagation delay1 A or B B or A — 0.25 ns tpd Propagation delay S A 1.6 5.0 ns Output enable time to High and Low level OE A or B 1.8 5.1 ns S B 1.6 5.2 ns Output disable time from High and Low level OE A or B 2.2 5.5 ns S B 1.0 5.0 ns ten tdis NOTE: 1.
