TIB82S105BCFN

Overview

The TIB82S105BCFN is a TTL-based field-programmable state machine manufactured by Texas Instruments. It functions as a Mealy-type logic sequencer with a maximum clock rate of 50 MHz. The device features a 6-bit internal state register and an 8-bit output register, both utilizing positive-edge-triggered S/R flip-flops. Typical power consumption is 600 mW. It includes 48 product terms (AND terms) and 14 sum terms (OR terms). The component operates within a temperature range of 0°C to 75°C and utilizes a 28-pin dual in-line package.

Feature Summary

• Supports clock frequencies up to 50 MHz for high-speed logic operations.
• Features automatic power-on presetting of all flip-flops to simplify system initialization.
• Contains 48 AND terms and 14 OR terms for flexible logic programming.
• Includes a dedicated pin for simultaneous presetting of registers or configurable output control.

Applications

• Embedded systems requiring flexible logic control.
• Automation equipment sequence control.
• Digital circuit designs needing rapid response times.

Part Context

The TIB82S105BCFN is part of the 82S105 series of programmable logic devices. It is functionally equivalent to the SN10501 but offers improved speed characteristics. The 'FN' suffix typically denotes a specific package variant, such as a plastic DIP, consistent with the standard 28-pin configuration described for this family.

Replacement Considerations

The SN10501A is identified as functionally equivalent to the TIB82S105BC. Designers should verify specific operational conditions regarding power-on and asynchronous presetting behaviors when substituting between these variants.
