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
