Way back in the day, analog/digital converters (ADCs) had simple, parallel interfaces, either TTL or high-level CMOS. Many of these converters could be clocked down to zero samples/second: once you ...

The HV509 is a 200V, 16-channel serial to parallel converter. The high voltage outputs and the backplane driver are designed to source and sink ±1.0mA. The high voltage outputs are controlled by a ...

Designed to drive printers and LCDs, the HV610, a 32-channel, serial-to-parallel converter, provides high-voltage, push-pull outputs in the realm of +50V/-40V. The chip’s outputs can be individually ...

The OXmPCI954 is designed to handle 15-Mbit/s asynchronous and 60-Mbit/s synchronous serial data rates. It integrates four high-performance UART channels, a 3.3-V PCI interface, and a local ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...
