HD74HC4518/HD74HC4520 Dual BCD Use Converters/Dual Binary Up Converters Description The HD74HC4518 dual BCD counter and the HD74HC4520 dual binary counter consist of two identical, independent, internally synchronous 4-stage counters. The counter stages are type D flip-flops, with interchangeable C
HD74HC4538 Dual Precision Retriggerable/Resettable Monostable Multivibrators Description Each multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit input. Also included is a clear input that when taken low resets the one
HD74HC4514 4-bit Latch/4-to-16-line Decoder Description This device presents a 4-to-16 line decoder with latched in puts. The HD74HC4514 presents a high level at the selected output. This device consists of four storage latches with common strobe and inhibit (G) inputs. When a low signal is applied
HD74HC4515 4-bit Latch/4-to-16-line Decoder Description This device presents 4-to-16 line decoder with latched inputs. The HD74HC4515 presents a low level at the selected output. This device consists of four storage latches with common strobe and inhibit (G) inputs. When a low signal is applied to
HD74HC4511 BCD-to-Seven Segment Latch/Decoder/Driver Description The HD74HC4511 provides the functions of a 4-bit storage latch, a BCD-to-seven-segment decoder, and an output driver. Lamp test (LT), blanking (BI), and latch enable (LE) inputs are used to test the display, to turn off or pulse-modul
HD74HC4543 BCD-to-Seven Segment Latch/Decoder/Driver Description This circuit contains a 4-bit latch, BCD-to-7 segment decoder, and 7 outpt drivers. Data on the input pins flow through to the output when the Latch Disable (LE) is high and is latched on the high to low transition of the LE input. Th
