While it is possible to drive GPIB pins directly from a microcontroller's GPIO ports, the electrical and protocol characteristics are challenging enough that most vendors implement GPIB through one of a set of available single-chip solutions.

A GPIB device can be a talker (sends information to the bus), listener (receives information from the bus), or controller, which manage the bus and connected devices. GPIB chips embedded in host-side GPIB interfaces (GPIB-USB, PCI-GPIB and so on) are generally all three: talker, listener, controller (TLC).

NEC µPD7210

Texas Instruments 9914A

National Instruments NAT9914A

National Instruments NAT4882

National Instruments TNT4882

The TNT4882 is a Talker/Listener ASIC which is software-compatible with the NAT4882.

National Instruments TNT5002

Talker/Listener ASIC

National Instruments TNT5004

Talker/Listener/Controller ASIC
