CD74HCT4511 Datasheet | Texas Instruments

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 m A at 4.5 V (CD74HCT4511) - 10 m A at 6 V ('HC4511) - Input latches for BCD code storage - Lamp test and blanking capability - Balanced propagation delays and transition times - Significant power reduction pared to LSTTL logic IC's - 'HC4511 - High noise immunity, NIL or NIH = 30% of VCC at VCC = 5 V - CD74HCT4511 - Direct LSTTL input logic patibility, VIL = 0.8 V Maximum, VIH = 2 V minimum - CMOS input patibility, II ≤ 1μA at VOL, VOH 2 Description 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.
