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

Synchronization of Cascaded Slave Device to

a Master Backplane Signal

■ Binary and BCD Inputs Decoded to Code B

(0 to 9, —, E, H, L, P, Blank)

■ Pin Compatible and Functionally Equivalent to ICM7211AM
