PLUS405-55 - Programmable logic sequencer

Description

The PLUS405-55 device is a bipolar, programmable state machine of the Mealy type.

Both the AND and the OR array are user-programmable.

All 64 AND gates are connected to the 16 external dedicated inputs (I0 - I15) and to the feedback paths of the 8 on-chip State Registers (QP0 - QP7).

Features

  • 66.7MHz minimum guaranteed clock rate.
  • 55MHz minimum guaranteed operating.
  • Functional superset of PLS105/105A.
  • Field-programmable (Ti-W fusible link).
  • 16 input variables.
  • 8 output functions.
  • 64 transition terms.
  • 8-bit State Register.
  • 8-bit Output Register.

www.DataSheet4U.com Philips Semiconductors Programmable Logic Devices Product specification Programmable logic sequencer (16 × 64 × 8) PLUS405-55 DESCRIPTION The PLUS405-55 device is a bipolar, programmable state machine of the Mealy type. Both the AND and the OR array are user-programmable. All 64 AND gates are connected to the 16 external dedicated inputs (I0 - I15) and to the feedback paths of the 8 on-chip State Registers (QP0 - QP7). Two complement arrays support complex IF-THEN-ELSE state transitions with a single product term (input variables C0, C1). All state transition terms can include True, False and Don’t Care states of the controlling state variables.
