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 74HC/HCT4511 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……
