Texas Instruments CD54HC4511
The CD54HC4511, CD74HC4511, and CD74HCT4511 are BCD-to-7 segment latch/decoder/ drivers with four address inputs (D0−D3), an activelow 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.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 4.5 V (CD74HCT4511) – 10 mA at 6 V ('HC4511)
● Input latches for BCD code storage
● Lamp test and blanking capability
● Balanced propagation delays and transition times
● Significant power reduction compared to LSTTL logic IC's
● 'HC4511 – High noise immunity, NIL or NIH = 30% of VCC at VCC = 5 V
● CD74HCT4511 – Direct LSTTL input logic compatibility, VIL = 0.8 V Maximum, VIH = 2 V minimum – CMOS input compatibility, II ≤ 1μA at VOL, VOH 2
