Product number (P/N): MM5760N,
Keywords/Tags: MM5760N
Date of intro-: ~1975, TimeKeeper IC's (sorted by Year): (Link), Case: Type = Dual In Line (DIL) 24,
Classification: / Part / Calculator-Chip,
Featuring: Logic-technology: VLSI (Very Large Scale Integration), calculator-on-a-Chip,
Info: The single-chip MM5760 Slide Rule Calculator was developed using a metal-gate, P-channel enhancement and depletion mode MOS/LSI technology with
the primary objective of low end-product cost.
Keyboard decoding and key debounce circuitry, all clock and timing generation and 7-segment output display encoding are included on-chip and
require no external components.
Segments can usually be driven directly from the MM5760, as it typically sources about 8.5 mA of peak current
The left-most digit is used for the negative sign or the decimal point of a number less than unity.
An internal power-on clear circuit clears all registers, including the memory, when VDD and Vss are initially applied to the chip.
Trailing zero suppression allows convenient reading of the left justified display, and conserves power.
Automatic display cutoff is included. If no key closure occurs for approximately 35 seconds, all numbers are blanked and all decimal points displayed.
The Ready output signal is used to indicate calculator status. It is useful in providing synchronization information during testing and
when the MM5760 is used with other logic or integrated circuits; e.g., with the MM5765 Programmer.
Thirty-two keys are arranged in a four-by-nine matrix.
In addition to seven arithmetic functions plus logarithmic, trigonometric and accumulating memory functions.
