ATV750B-10DM/883

Programmable Logic Device Pld Overview

The ATV750B-10DM/883 is a high-speed UV-erasable programmable logic device (PLD) manufactured by Microchip Technology. It operates on a +5V supply and features a maximum propagation delay of 10 ns with an external operating frequency up to 74 MHz. The device provides 20 sum terms, 20 flip-flops, and 10 I/O pins within a 24-lead windowed ceramic dual inline package (Cerdip). It supports full military temperature ranges from -55°C to +125°C and complies with MIL-STD-883 Class B requirements.

Programmable Logic Device Pld Feature Summary

• High-density architecture offering 20 sum terms and 20 individually configurable D- or T-type flip-flops in a 24-pin package.
• Maximum pin-to-pin propagation delay of 10 ns, supporting external feedback frequencies up to 74 MHz.
• Supports both product term clocking and direct input pin clocking for each flip-flop.
• Includes asynchronous reset and synchronous preset capabilities for all registers.

Programmable Logic Device Pld Applications

• Military and aerospace digital logic systems requiring MIL-STD-883 compliance.
• Complex state machine implementations utilizing buried flip-flops and independent feedback paths.
• High-speed timing circuits requiring uniform and predictable delays.
• Replacement for legacy 22V10 architectures in existing hardware designs.

Programmable Logic Device Pld Procurement Notes

Verify that the component matches the specific speed grade (-10) and package type (24DW3 Cerdip) required for the design. Confirm that the supplier provides documentation verifying MIL-STD-883 Class B compliance, as this is a critical specification for this part number. Ensure the UV erasable window remains covered during operation to prevent unintended data loss.

Programmable Logic Device Pld Selection Notes

Select this device when high logic density is required within a constrained 24-pin footprint. The -10 speed grade offers a balance between performance and power consumption compared to faster variants. Consider the ATF750C series for new commercial designs, as the ATV750B is noted for continued availability but not recommended for new designs. Verify compatibility with existing PLD programming software if migrating from older ATV750(L) devices.

Programmable Logic Device Pld Part Context

The ATV750B series represents an advanced generation of Atmel (now Microchip) PLDs, serving as a superset of the standard 22V10 architecture. It distinguishes itself through enhanced flexibility, including individual clocking options for flip-flops and increased product terms. While commercial and industrial versions are obsolete, the military-grade /883 variants remain available for specialized applications requiring radiation hardness and wide temperature tolerance.

Programmable Logic Device Pld Replacement Considerations

The ATF750C series is the designated replacement for commercial and industrial ATV750B versions. For military applications, multiple ATF22V10 devices are recommended for new designs instead of continuing to use the ATV750B. Direct functional substitution requires verification of pinout compatibility and timing constraints.
