BCD to 7-segment latch/decoder/driver
FEATURES Latch storage of BCD inputs Blanking input Lamp test input Driving common cathode LED displays Guaranteed 10 mA drive capability per output Output capability: non-standard ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT4511 are high-speed Si-gate CMOS devices and are pin compatible with “4511” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4511 are BCD to 7-segment latch/decoder/drivers with four address inputs (D1 to D4), an active LOW latch enable input (LE), an active LOW QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns APPLICATIONS Driving LED displays

ripple blanking input (BI), an active LOW lamp test input (LT), and seven active HIGH segment outputs (Qa to Qg). When LE is LOW, the state of the segment outputs (Qa to Qg) is determined by the data on D1 to D4. When LE goes HIGH, the last data present on D1 to D4 are stored in the latches and the segment outputs remain stable. When LT is LOW, all the segment outputs are HIGH independ……
