1 ps2092b 09/19/02 product description pericom semiconductor?s pi74lcx series of logic circuits are produced using the company?s advanced 0.6 micron cmos technology achieving high speed while maintaining low power operation. the pi74lcx16543 is 16-bit latched transceivers organized with two sets of eight d-type latches with separate input and output controls for each set. for data flow from a to b, for example, the a-to-b enable (xceab) input must be low in order to enter data from xax or to take data from xbx, as indicated in the truth table. with xceab low, a low signal makes the a-to-b latches transparent; a subsequent low-to-high transition of the xleab signal puts the a latches in the storage mode and their outputs no longer change the a inputs. with xceab and xoeab both low, the 3-state b output buffers are active and reflect the data present at the output of the a latches. control of data from b to a is similar, but uses the xceab, xleab, and xoeab inputs. the pi74lcx16543 can be driven from either 3.3v or 5.0v devices allowing this device to be used as a translator in a mixed 3.3v/5.0v system. 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 pi74lcx16543 fast cmos 16-bit latched transceivers product features ? functionally compatible with fct3, lvt, and 74 series 16543 families of products ? tri-state outputs ? 5v tolerant inputs and outputs ? 2.0v-3.6v v cc supply operation ? balanced sink and source output drives (24 ma) ? low ground bounce outputs ? power down high impedance inputs and outputs ? supports live insertion ? esd protection exceeds 2000v, human body model 200v, machine model ? packages available: ? 56-pin 240-mil wide plastic tssop (a) ? 56-pin 300-mil wide plastic ssop (v) logic block diagram 1 b 0 d c 1 a 0 to 7 other channels d c 1 leab 1 ceab 1 oeab 1 leba 1 ceba 1 oeba 2 b 0 d c 2 a 0 to 7 other channels d c 2 leab 2 ceab 2 oeab 2 leba 2 ceba 2 oeba
