CD74HC4511E

The CD74HC4511E is a 1-channel high speed CMOS logic BCD-to-7 Segment Latch/Decoder/Driver with four address inputs D0 to D3, an active-low blanking (BL) input, lamp-test (LT) input and a latch-enable (LE) input that, when high, enables the latches to store the BCD inputs. When LE is low, the latches are disabled, making the outputs transparent to the BCD inputs. This device has standard-size output transistors, but is capable of sourcing (at standard VOH levels) up to 7.5mA at 4.5V. The HC types can supply up to 10mA at 6V.

• Input latches for BCD code storage
• Lamp test and blanking capability
• Balanced propagation delays and transition times
• Significant power reduction compared to LSTTL logic ICs
• CMOS Input compatibility
