tc7wpb9306,9307fc/fk 2014-03-01 1 toshiba cmos digital integrat ed ci rcuit silicon monolithic tc7wpb9306fc, tc7wpb9307fc tc7wpb9306fk, TC7WPB9307FK low voltage/low power 2-bit dual supply bus switch the tc7wpb9306 and tc7wpb9307 are cmos 2-bit dual-supply bus switches that can provide an interface between two nodes at different voltage levels. these devices can be connected to two independent power supplies. v cca supports 1.8-v, 2.5-v and 3.3-v po wer supplies, whereas v ccb supports 2.5-v, 3.3-v and 5. 0v power supplies. bidirectional level-shifting is possible by simply adding external pull-up resistors between the an/bn data lines and the v cca / v ccb supplies. there is no restriction on the relative magnitude of the an and bn volt ages; both the an and bn data lines can be pulled up to arbitrary power supplies. the enable signal can be used to disable the device so that the buses are effectively isolated. the output enable ( oe :tc7wpb9307, oe:tc7wpb9306) input is common for all the two-bits of the data lines; thus these device are used as a single two-bits bus switch. for the tc7wpb9306, output enable (oe) is active-high: when oe is high, the switch is on; when lo w, the switch is off. for the tc7wpb9307, output enable ( oe ) is active-low: when oe is low, the switch is on; when high, the switch is off. the tc7wpb9306 and tc7wp9307 supports power-down protection at the oe ,oe input, with oe ,oe being 5.5-v tolerant. the channels consist of n-type mosfets. all the inputs provide protec tion against electrostatic discharge. features ? operating voltage:1.8-v to 2.5-v, 1.8-v to 3.3-v, 1.8-v to 5.0-v, 2.5-v to 3.3-v, 2.5-v to 5.0-v or 3.3-v to 5.0-v bidirectional interface ? operating voltage: v cca = 1.65 to 5.0 v, v ccb = 2.3 to 5.5 v ? low on-resistance: r on = 5.0 (typ.)
