1 / 9 page SN65518, SN75518 VACUUM FLUORESCENT DISPLAY DRIVERS SLDS004B – MARCH 1983 – REVISED MAY 1990 Copyright © 1990, Texas Instruments Incorporated 4–1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 • Each Device Drives 32 Lines • 60-V Output Voltage Swing Capability • 25-mA Output Source Current Capability • High-Speed Serially Shifted Data Input • Latches on All Driver Outputs description The SN65518 and SN75518 are monolithic BIDFET† integrated circuits designed to drive a dot matrix or segmented vacuum fluorescent display. Each device consists of a 32-bit shift register, 32 latches, and 32 output AND gates. Serial data is entered into the shift register on the low-to-high transition of CLOCK. While LATCH ENABLE is high, parallel data is transferred to the output buffers through a 32-bit latch. Data present in the latch during the high-to-low transition of LATCH ENABLE is latched. When STROBE is low, all Q outputs are enabled. When STROBE is high, all Q outputs are low. Serial data output from the shift register may be used to cascade additional devices. This output is not affected by LATCH ENABLE or STROBE. The SN65518 is characterized for operation from –40 °C to 85°C. The SN75518 is characterized for operation from 0 °C to 70°C. † BIDFET – Bipolar, double-diffused, N-channel and P-channel MOS transistors on same chip. This is a patented process. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 VCC2 SERIAL OUT Q32 Q31 Q30 Q29 Q28 Q27 Q26 Q25 Q24 Q23 Q22 Q21 Q20 Q19 Q18 Q17 STROBE GND VCC1 DATA IN Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 Q9 Q10 Q11 Q12 Q13 Q14 Q15 Q16 LATCH ENABLE CLOCK N PACKAGE (TOP VIEW) Q4 Q5 Q6 Q7 Q8 Q9 Q10 Q11 Q12 Q13 NC 39 38 37 36 35 34 33 32 31 30 29 18 19 7 8 9 10 11 12 13 14 15 16 17 Q29 Q28 Q27 Q26 Q25 Q24 Q23 Q22 Q21 Q20 Q19 20 21 22 23 FN PACKAGE (TOP VIEW) 54 3 2 1 644 42 41 40 43 24 25 26 27 28 NC – No internal connection PRODUCTION DATA information is current as of publication date.
