1 / 8 page 1 Data sheet acquired from Harris Semiconductor SCHS245 Features • Buffered Inputs • Typical Propagation Delay - 4ns at VCC = 5V, TA = 25 oC, C L = 50pF • Exceeds 2kV ESD Protection MIL-STD-883, Method 3015 • SCR-Latchup-Resistant CMOS Process and Circuit Design • Speed of Bipolar FAST™/AS/S with Significantly Reduced Power Consumption • Balanced Propagation Delays • AC Types Feature 1.5V to 5.5V Operation and Balanced Noise Immunity at 30% of the Supply • ±24mA Output Drive Current - Fanout to 15 FAST™ ICs - Drives 50 Ω Transmission Lines Description The CD74AC245 and CD74ACT245 are octal-bus transceiv- ers that utilize the Harris Advanced CMOS Logic technology. They are non-inverting three-state bidirectional transceiver- buffers intended for two-way transmission from “A” bus to “B” bus or “B” bus to “A”. The logic level present on the direction input (DIR) determines the data direction. When the output enable input (OE) is HIGH, the outputs are in the high- impedance state.
