Компоненты Описание : BUS COMPATIBLE 4-DIGIT CMOS DECODER/DRIVER

GENERAL DESCRIPTION
The TC7211AM (LCD Decoder/driver) is a CMOS direct drive, 4-digit, 7-Segment display decoder and driver. The TC7211AM drives conventional LCDs. An RC os cillator, divider chain, backplane driver, and 28-Segment outputs are provided on a single CMOS chip. The Segment drivers supply square waves of the same frequency as the backplane, but in-phase for an OFF Segment and out-of-phase for an ON Segment. The net DC voltage applied between driver Segment and backplane is near zero maximizing display lifetime.
The four bit binary input is decoded into the seven Segment alphanumeric code known as "Code B". The "Code B" output format results in a 0 to 9,—, E, H, L, P or blank display. True BCD or binary inputs will be correctly de coded to the seven Segment display format.

FEATURES
■ 4-Digit Non-Multiplexed 7-Segment LCD Outputs
   With Backplane Driver
■ Input and Digit Select Data Latches
■ RC Oscillator On-Chip Generates Backplane
   Drive Signal
■ Eliminates DC Bias Which Degrades LCD Life
■ Backplane Input/Output Pin Permits

The µPD16431A is an LCD controller/driver that enables display of Segment type LCDs of 1/2, 1/3, or 1/4 duty cycle. This controller/driver has 56 Segment output lines of which eight can also be used as LED output lines. Because the LCD driver contained in the µPD16431A has separate logic and power supply, up to 6.5 V of LCD drive voltage can be set. In addition, key source output lines for key scanning and key input data lines are also provided, so that the µPD16431A is ideal for applications in the front panel of an automobile stereo system.

FEATURES
• Various display modes
    1/2 duty: 112 Segment outputs or 96 Segment outputs + 8 LED outputs
    1/3 duty: 168 Segment outputs or 144 Segment outputs + 8 LED outputs
    1/4 duty: 224 Segment outputs or 192 Segment outputs + 8 LED outputs
• Key scan circuit (key source outputs are shared with LCD driver outputs)
• Independent LCD driver power supply VLCD (can be set to VDD to 6.5 V)
• Serial data input/output (SCK, STB, DATA)
• On-chip oscillator incorporated
• Power-ON reset circuit
