The Am29C861A is a 10-bit t11 r,;,_:tional transceiver; the Am29C863A is a 9-bit tram, ,•i·,er with NORed out­ put enables for maximum contriJ lluxibility. Each device features data inputs with 20( 11''•1 typical input hys­ teresis to provide improved -,ois.e immunity. The Am29C861A and Am29C86� ' a"•3 produced with AM D's exclusive CS11SA CMC : '. . process, and features a typical propagation delay of 4 , c1s well as an output current drive of 48 mA. 1 The Am29C861A and Am29Cf ,;::,� incorporate AM D's proprietary edge-controlled out Juli in order to minimize simultaneous switching noise (:found bounce), under­ shoots and overshoots. By coI11 1·:>lli11g the output tran­ sient currents, ground bounce : 1-d output ringing have been greatly reduced. A modified AMO output provides a stable, usable voltage level in less time than a non­ controlled output. Additionally, speed degradation due to increasing num­ ber of outputs switching is reduced. Together, these benefits of edge-rate control result in signilicant in­ crease in system performance despite a minor increase in device propagation delay.* A unique 1/0 circuitry which utilizes n-channel pull-up transistors (eliminating the parasitic diode to Vee) pro­ vides for high-impedance outputs during power-off and power-up/down sequencing, thus providing glitch-free operation for card-edge and other active bus applications. The Am29C861A and Am29C863A are available in the standard package options: DIPs, PLCCs, and SOICs. • For more details refer to a Minimizat,." : i Ground Bounce Through Output Edge-Rate Control Application Note (See Chapter 3).
