The PAL family continued to evolve into the late 1980s, with faster, lower-power devices, including ones that could be reprogrammed. The most complex device type developed was probably the PAL22V10, ...

Programmable logic has come a long way from the simple devices we started out with. Remember Programmable Array Logic, or PALs? In bipolar technology the ICC on even a small PAL was over 100mA, and ...

Members can download this article in PDF format. For market growth to occur at desired levels, suppliers must meet consumer demand for compact electronic devices that integrate multiple functions. To ...

Programmable logic devices have claimed their place in the hobbyist world, with more and more projects showing up that feature either a CPLD or their bigger sibling, the FPGA. That place is rightfully ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

When the programmable logic device first appeared in the first half of the 1980s, it was used almost entirely as a means of fixing design errors – the so called 'glue logic'. But with evolutions in ...

Programmable-logic devices are the fastest growing segment of the logic-device family, for two fundamental reasons. Their ever-increasing gate count per device gathers up functions that you might ...

After one of my engineers told me that she had found a typo in her hardware, I thought just how far design has come in the last 30 years and more. Back then, the analog section of a system consisted ...
