| Features |
two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
2. Features and benefits
• Supply voltage range from 4.5 to 5.5 V • Octal bus interface • 3-State buffers • BiCMOS high speed and output drive • Output capability: +64 mA/ –32 mA • Direct interface with TTL levels • Power-up 3-State ... |
