description
The 'FCT827T devices are 10-bit bus drivers that provide high-performance bus-interface buffering for wide data/address paths or buses carrying parity. The 10-bit buffers have NANDed output enables for maximum control flexibility. The 'FCT827T devices are designed for high-capacitance-load drive capability, while providing low-capacitance bus loading at both inputs and outputs. All outputs are designed for low-capacitance bus loading in the high-impedance state.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The package thermal impedance is calculated in accordance with JESD 51-7.

Typical values are at VCC = 5 V, TA = 25°C. Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample-and-hold techniques are preferable to minimize internal chip heating and more accurately reflect operational values. Otherwise, prolonged shorting of a high output can raise the chip temperature well above normal and cause invalid readings in other parametric tests. In any sequence of parameter tests, IOS tests should be performed last. § Per TTL-driven input (VIN = 3.4 V); all other inputs at VCC or GND

Ci Co ¶ This parameter is derived for use in total power-supply calculations. # IC = ICC + ICC × DH × NT + ICCD (f0/2 + f1 × N1) Where: IC = Total supply current ICC = Power-supply current with CMOS input levels ICC = Power-supply current for a TTL high input (VIN = 3.4 V) DH = Duty cycle for TTL inputs high NT = Number of TTL inputs at DH ICCD = Dynamic current caused by an input transition pair (HLH or LHL) f0 = Clock frequency for registered devices, otherwise zero f1 = Input signal frequency N1 = Number of inputs changing at f1 All currents are in milliamperes and all frequencies are in megahertz. || Values for these conditions are examples of the ICC formula.
