Typical Applications
EPM5016PC-1 is suitable for 6 applications: Microprocessor Address Decoding, Glue Logic Integration in VMEbus Systems, Peripheral Replacement for 74LS TTL Logic, Finite State Machine Controllers, ISA / PC/104 Bus Interface Logic, Industrial Instrumentation and Test Equipment.
Microprocessor Address Decoding
The EPM5016PC-1 is widely used to replace discrete 74LS138, 74LS139, and 74LS154 decoder chips in 8-bit and 16-bit microprocessor systems such as Intel 8086, Motorola 68000, and Zilog Z80 designs. With 16 macrocells and combinatorial output capability, the device can decode the full 16-bit address space into 8 to 12 chip-select signals while consuming a single 20-pin DIP socket. Designers benefit from consolidating multiple TTL decoders into one part, reducing board area and improving noise margin on the address bus. The 35 ns tPD is sufficient for 8 MHz 8086 and 10 MHz 68000 timing without wait states. Quoted from typical MAX 5000 application notes: a single EPM5016 can replace four to six 74LS series packages.
Recommended
Glue Logic Integration in VMEbus Systems
In legacy VMEbus backplane designs, the EPM5016PC-1 integrates scattered 74LS244 buffers, 74LS245 transceivers, and 74LS373 latches into a single 5 V programmable device. The 16 dedicated inputs accept bus arbitration signals such as BR0-BR3, BBSY, and BGACK, while the output macrocells drive control lines like DTACK, AS, and DS with TTL-compatible drive strength. The through-hole PDIP-20 package suits the through-hole backplane assemblies typical of 1980s-1990s VME hardware. Note that the 35 ns tPD adds one wait state at VME's 16 MHz bus speed; the -15 or -20 grade is preferred for backplane designs requiring zero-wait-state operation.
Recommended
Peripheral Replacement for 74LS TTL Logic
The EPM5016PC-1 consolidates multiple 74LS series small-scale integration gates - 74LS00, 74LS08, 74LS32, 74LS86, 74LS151, 74LS153 - into a single 5 V through-hole package, reducing BOM count and PCB area in legacy industrial controllers. With 200 usable gates and 16 macrocells, the device replaces 4 to 8 TTL packages while preserving the original 5 V logic levels and TTL input thresholds. The bidirectional I/O pins simplify wiring of mixed combinatorial and registered logic that would otherwise require separate gate and flip-flop packages. EEPROM re-programmability allows late-stage design changes without board rework, valuable in low-volume industrial product runs.
Recommended
Finite State Machine Controllers
The EPM5016PC-1 implements Moore and Mealy state machines of up to 16 states using its macrocell flip-flops with D, T, JK, or SR modes. Each macrocell provides a programmable sum term that combines product terms from the AND array, allowing efficient encoding of state transition logic. The dedicated feedback path from every macrocell to the Programmable Interconnect Array (PIA) supports fully buried state registers when I/O pins are scarce, freeing output pins for control signals. Typical applications include serial protocol controllers (RS-232, RS-485), stepper motor sequencers, and watchdog timers. The 35 ns tPD and 62 MHz fMAX support state machines clocked at rates up to 50 MHz with conservative timing margin.
Recommended
ISA / PC/104 Bus Interface Logic
Legacy ISA bus add-in cards and PC/104 embedded modules use the EPM5016PC-1 to implement address decoding, wait-state generation, and interrupt acknowledge logic in a single 5 V through-hole device. The 16-macrocell capacity handles the 24-bit ISA address space divided into I/O and memory regions, generating chip-select signals for peripheral ICs while decoding the interrupt controller cascade chain. The PDIP-20 package fits the through-hole card edge connectors common to industrial PC/104 stacks. Designers migrating ISA logic to PC/104-Plus or PCI should note that no drop-in upgrade exists - a redesign around a modern MAX II CPLD is required for 3.3 V PCI signaling.
Recommended
Industrial Instrumentation and Test Equipment
The EPM5016PC-1 is deployed in legacy bench-top instruments - oscilloscopes, spectrum analyzers, signal generators, and digital multimeters - where it replaces custom gate arrays and discrete logic for timing, sequencing, and front-panel decoding. The 5 V single-supply operation matches the power architecture of instruments designed before the 3.3 V transition. Macrocells generate precision timing pulses for ADC/DAC control, multiplex front-panel switch matrices, and decode rotary encoder quadrature signals. The through-hole PDIP-20 package suits the through-hole assembly used in field-repairable instruments. Sustainment programs for military and aerospace test equipment continue to demand this part long after consumer-market obsolescence.

Key Differentiators
- Through-hole PDIP package for legacy 5 V systems (vs EPM5016DC-20)
- Slowest speed grade offers cost advantage (vs EPM5016DC-15)
- Industry-standard 5 V TTL compatibility (vs EPM5016DI-20)
Design Notes
The EPM5016PC-1 in PDIP-20 requires a 0.3 inch wide through-hole footprint with 0.1 inch (2.54 mm) pin pitch. Decouple VCC (pin 20) to GND (pin 12) with a 0.1 uF ceramic capacitor placed within 5 mm of the device; add a 10 uF tantalum bulk capacitor on the same supply rail for switching transients. Keep clock and high-speed output traces short to avoid ground bounce - this part has TTL drive strength and can source/sink 24 mA per I/O, but simultaneous switching of more than 8 outputs at 50 MHz may cause VCC sag below 4.75 V.
Do not assume the -1 speed grade meets 25 MHz 8086 timing - the 35 ns tPD exceeds the 8086 tCO requirement and will require one wait state. Choose the -15 or -20 grade if zero-wait-state operation is needed. Also note that MAX+PLUS II design software is no longer distributed by Intel/Altera; use Quartus II legacy support or third-party MAX+PLUS II versions to compile JEDEC files. Programming requires an Altera ByteBlaster or MasterBlaster cable; modern USB programmers do not support MAX 5000.
Estimated: at 5 V VCC, 50 mA ICC, and 50% output toggle rate, the EPM5016PC-1 dissipates approximately 250 mW. With theta_JA of approximately 80 C/W for PDIP-20, junction temperature rise above ambient is about 20 C - well within the 0 C to +70 C commercial range. At 70 C ambient with no airflow, junction reaches 90 C, still within the 125 C maximum. No heatsink is required for typical through-hole designs.
