Texas Instruments 74ACT11590
The 74ACT11590 contains an 8-bit binary counter that feeds an 8-bit storage register. The storage register has parallel outputs. The binary counter features a direct clear (CCLR) input and a count-enable (CCKEN) input.ą
● Inputs Are TTL-Voltage Compatible
● Parallel Registered Outputs
● Internal Counters Have Direct Clear
● Flow-Through Architecture Optimizes PCB Layout
● Center-Pin VCC and GND Configurations Minimize High-Speed Switching Noise
● EPIC (Enhanced-Performance Implanted CMOS) 1-µm Process
● 500-mA Typical Latch-Up Immunity at 125°C
● Package Options Include Plastic Small-Outline Packages and Standard Plastic 300-mil DIPs 74ACT11590 8ĆBIT BINARY COUNTER WITH REGISTERED 3ĆSTATE OUTPUTS SCAS195 − D3989, MARCH 1992 − REVISED APRIL 1993 DW OR N PACKAGE (TOP VIEW) QB QC QD GND GND GND GND QE QF QG 1 2 3 4 5 6 7 8 9 10 20 QA 19 CCK 18 CCKEN 17 CCLR 16 VCC 15 VCC 14 OE 13 RCK 12 RCO 11 QH description The storage register has parallel outputs. Separate clocks are provided for both the binary counter and storage register. For cascading, a ripple-carry (RCO) output is provided. Expansion is easily accomplished for two stages by connecting RCO of the first stage to CCKEN of the second stage. Cascading for larger count chains can be accomplished by connecting RCO of each stage to CCK of the following stage.
