DESCRIPTION

The M74HC4543 is an high speed CMOS BCD-TO-7 SEGMENT DECODER WITH LCD DRIVER fabricated with silicon gate C2MOS technology.

This device consists of BCD-TO-7 segment decoder with a BCD input latch and a 7-segment driver for a liquid crystal display (LCD). When any illegal BCD input signal is applied or input BI is held high, the display is blanked.

■ HIGH SPEED:

tPD = 14ns (TYP.) at VCC = 6V

■ LOW POWER DISSIPATION:

ICC = 4µA(MAX.) at TA=25°C

■ HIGH NOISE IMMUNITY:

VNIH = VNIL = 28 VCC (MIN.)

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 4mA (MIN)

■ BALANCED PROPAGATION DELAYS:

tPLH ≅ tPHL

■ WIDE OPERATING VOLTAGE RANGE:

VCC (OPR) = 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4543
