Product Summary
The SMC34C60QFP is a parallel port interface chip. In addition to Standard (Compatible) printer ports, the SMC34C60QFP supports PS/2 (bi-directional), EPP, and ECP ports. Up to eight peripherals may be daisy chained between the computer and the printer. Printer operation is unaffected. The SMC34C60QFP also provides a piezo transducer driver for battery-powered systems. The transducer will signal low battery with two repeated beeps. If the cable to the computer is disconnected, or if the host is dormant for about a minute, the transducer will signal inactivity with four beeps. Additionally, a power-down signal can be provided to external circuitry to automatically shut down system power during inactivity.
