- Package Includes: 1 X 74HC4511 BCD to 7 Segment Latch/Decoder/Drivers IC (744511) DIP-16 Package
Features:
- 2-V to 6-V VCC Operation ('HC4511)
- 4.5-V to 5.5-V VCC Operation (CD74HCT4511)
- High-Output Sourcing Capability - 7.5 mA at 4.5V (CD74HCT4511) - 10 mA at 6V ('HC4511)
- Input Latches for BCD Code Storage
The CD54HC4511, CD74HC4511, and CD74HCT4511 are BCD-to-7 segment latch/decoder/drivers with four address inputs (D0-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. These devices have standard-size output transistors but are capable of sourcing (at standard VOH levels) up to 7.5 mA at 4.5V. The HC types can supply up to 10 mA at 6V.
Other features include lamp test and blanking capability, balanced propagation delays and transition times, significant power reduction compared to LSTTL logic ICs, high noise immunity for HC4511, and direct LSTTL input logic compatibility for CD74HCT4511.
