M74HC4543 Datasheet PDF - ST Microelectronics

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
