SCCS034 - September 1994 - Revised March 2000 · Sink current
10-Bit Buffer
Source current 64 mA (Com'l), 32 mA (Mil) 32 mA (Com'l), 12 mA (Mil)
Features
· Function, pinout, and drive compatible with FCT, F, and AM29827 logic · FCT-C speed at 4.4 ns max. (Com'l) FCT-A speed at 5.0 ns max. (Com'l) · Reduced VOH (typically = 3.3V) versions of equivalent FCT functions · Edge-rate control circuitry for significantly improved noise characteristics · Power-off disable feature · ESD > 2000V · Matched rise and fall times · Fully compatible with TTL input and output logic levels
Functional Description
The FCT827T 10-bit bus driver provides high-performance bus interface buffering for wide data/address paths or buses carr ying parity. The 10-bit buffers have NAND-ed output enables for maximum control flexibility. The FCT827T is 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 and are designed with a power-off disable feature to allow for live insertion of boards.

Notes: 2. Unless otherwise noted, these limits are over the operating free-air temperature range. 3. Unused inputs must always be connected to an appropriate logic voltage level, preferably either VCC or ground. 4. TA is the "instant on" case temperature. 5. Typical values are at VCC=5.0V, TA=+25°C ambient. 6. This parameter is specified but not tested. 7. Not more than one output should be shor ted at a time. Duration of shor t should not exceed one second. The use of high-speed test apparatus and/or sample and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shor ting of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter tests, IOS tests should be performed last.
