CD54HC4511中文资料高速 CMOS 逻辑 BCD 至 7 段锁存器/解码器/驱动器数据手册TI规格书

描述 Description

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 4.5 V. The HC types can supply up to 10 mA at 6 V.
