M74HC4511 BCD TO 7 SEGMENT LATCH/DECODER DRIVER ■ ■ ■ ■ ■ ■ ■ HIGH SPEED: tPD= 23ns (TYP.) at VCC = 6V LOW POWER DISSIPATION: ICC = 4µA(MAX.) at TA=25°C HIGH NOISE IMMUNITY: VNIH = V NIL = 28 % VCC (MIN.) HIGH SOURGE CURRENT : |IOH| = 20 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4511 DESCRIPTION The M74HC4511 is an high speed CMOS BCD-TO-7 SEGMENT LATCH/DECODER/ DRIVER fabricated with silicon gate C2MOS technology. The segment output driver has large IOH capability which enables common cathode leds to be directly driven. When lamp test (LT) is taken "L", all segment outputs will go to "H", and when blanking (BI) is taken "L" and LT is taken "H" all segment outputs will go to "L". DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC4511B1R M74HC4511M1R T&R M74HC4511RM13TR M74HC4511TTR These functions operate regardless of other inputs and are used to test the display. Input BI is used to pulse-modulate the brightness of the display. When an error input code (over 10) is applied to the BCD input, all segment outputs will go "L" (turn off). All inputs are equipped with protection circuits against static discharge and transient excess voltage.
