The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. Output Enable (OE) and select-control (S) inputs select the appropriate B1 and B2 outputs for the A-input data. Internal diode allows voltage level shifting from 5 V inputs to 3.3 V outputs. The CBTD3257 is characterized for operation from –40 to +85 °C.

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 Sep 09 4 Philips Semiconductors Preliminary data Quad 1-of-2 multiplexer/demultiplexer with level shifting CBTD3257 AC CHARACTERISTICS Tamb = –40 to +85 °C; CL = 50 pF LIMITS SYMBOL tpd tpd ten tdis PARAMETER Propagation delay1 Propagation delay Output enable time to High and Low level Output disable time from High and Low level FROM (INPUT) A or B S OE S OE S TO (OUTPUT) B or A A A or B B A or B B VCC = +5.0 V ±0.5 V MIN — 1.6 1.8 1.6 2.2 2.0 MAX 0.25 11.0 11.2 10.8 6.0 8.0 ns ns ns ns ns ns UNIT NOTE: 1.
