3 / 9 page IDT54/74FCT16646T/AT/CT/ET, 162646T/AT/CT/ET FAST CMOS 16-BIT BUS TRANSCEIVER/REGISTER MILITARY AND COMMERCIAL TEMPERATURE RANGES 5.13 3 PIN DESCRIPTION FUNCTION TABLE (2) CAPACITANCE (TA = +25 °C, f = 1.0MHz) 2540 tbl 01 NOTE: 1. This parameter is measured at characterization but not tested. 2540 tbl 02 NOTES: 2540 tbl 03 1. The data output functions may be enabled or disabled by various signals at the x OE or xDIR inputs. Data input functions are always enabled, i.e. data at the bus pins will be stored on every LOW-to-HIGH transition on the clock inputs. 2. H = HIGH Voltage Level L = LOW Voltage Level X = Don't Care ↑ = LOW-to-HIGH Transition ABSOLUTE MAXIMUM RATINGS (1) Symbol Parameter(1) Conditions Typ. Max.

Stresses greater than those listed under ABSOLUTE MAXIMUM RAT- INGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. All device terminals except FCT162XXXT Output and I/O terminals. 3. Output and I/O terminals for FCT162XXXT. |
