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 V See Figure 1 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 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 11.0 ns ten Output enable time to High and Low level OE A or B 1.8 11.2 ns S B 1.6 10.8 ns Output disable time from High and Low level OE A or B 2.2 6.0 ns S B 2.0 8.0 ns tdis NOTE: 1.
