74HC4511 74HCT4511 BCD to 7-segment latch/decoder/driver Rev. 3 15 November 2016 Product data sheet 1. General description The 74HC4511 74HCT4511 is a BCD to 7-segment latch/decoder/driver with four address inputs (A, B, C, D), a latch enable input (LE), a ripple blanking input (BI), a lamp test input (LT), and seven segment outputs (a to g). When LE is LOW, the state of the segment outputs (a to g) is determined by the data on A to D. When LE goes HIGH, the last data present on A to D are stored in the latches and the segment outputs remain stable. When LT is LOW, all the segment outputs are HIGH independent of all other input conditions. With LT HIGH, a LOW on BI forces all segment outputs LOW. The inputs LT and BI do not affect the latch circuit. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . CC 2. Features and benefits Complies with JEDEC standard no. 7A Input levels: For 74HC4511: CMOS level For 74HCT4511: TTL level Latch storage of BCD inputs Blanking input Lamp test input Driving common cathode LED displays Guaranteed 10 mA drive capability per output ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Specified from 40 C to +85 C and 40 C to +125 C 3.
