- 22 MHz maximum clock frequency supports synchronous registered designs including state machines, address decoders, and bus arbitration logic in medium-speed digital systems
- 24-pin hermetic ceramic DIP package (JESD-30 R-GDIP-T24) delivers high-reliability operation in extended temperature environments, suitable for military and industrial legacy designs
- PAL-type architecture is compatible with industry-standard PALASM and WinCUPL programming tools, preserving decades of existing logic equation libraries and design files
Applications
The TIBPAL22V10AMJTB is used in legacy digital logic applications including address decoding, bus arbitration, glue logic replacement, and finite state machine implementation in industrial controllers, VMEbus systems, and embedded computer boards. Its 22-input PAL architecture consolidates multiple discrete TTL gates into a single programmable device, reducing board space and improving reliability in long-lifetime industrial and defense systems. The ceramic DIP package also makes it a preferred choice for military avionics and space-heritage equipment requiring hermetic packaging.

Frequently Asked Questions
What does the PAL22V10 architecture provide in the TIBPAL22V10AMJTB?
The PAL22V10 architecture provides 22 total inputs (11 dedicated inputs plus 10 bidirectional I/O), 10 output macrocells, and 132 product terms organized in a programmable AND-array with fixed OR-array. Each output macrocell includes a configurable register and output enable, allowing implementation of both combinatorial and registered (clocked) logic functions in a single device.
What is the maximum clock frequency of the TIBPAL22V10AMJTB?
The TIBPAL22V10AMJTB supports a maximum clock frequency of 22 MHz for synchronous registered operations. This speed grade is suitable for state machines, synchronous counters, and registered address decoders in medium-speed digital systems operating at standard TTL voltage levels typical of legacy backplane and industrial controller designs.
What package does the TIBPAL22V10AMJTB use?
The TIBPAL22V10AMJTB is housed in a 24-pin hermetic ceramic DIP package (JESD-30 code R-GDIP-T24). The ceramic hermetic package provides superior protection against moisture and contaminants compared to plastic DIPs, making it suitable for high-reliability applications in military electronics, avionics, and industrial equipment with long service life requirements.
How is the TIBPAL22V10AMJTB programmed?
The TIBPAL22V10AMJTB is a one-time programmable (OTP) PAL device programmed using a standard device programmer with JEDEC-format fuse map files. Logic equations are typically written in PALASM, ABEL, or WinCUPL hardware description languages and compiled to a JEDEC file. The '22V10' designation indicates compatibility with the industry-standard PAL22V10 fuse map format widely supported by programming tools.
What are common replacements or alternatives for the TIBPAL22V10AMJTB?
Direct functional equivalents include the AMD/Lattice PALCE22V10 and the National Semiconductor GAL22V10, which are pin-compatible and electrically equivalent. The GAL22V10 offers the additional advantage of being electrically erasable (E2PROM-based) for re-programmability. For new designs, CPLDs such as the Lattice ispMACH 4000 or Xilinx XC2C32A offer far greater capacity while maintaining PAL-like architectures.
