74HC595 74HC595N 74HC595D 8-BIT Shift Register (2 ชิ้น)

74HCxxx : High-speed CMOS Circuit.
VCC : 2-6 V
- เหมาะสำหรับใช้งานร่วมกับ MCU/บอร์ด/โมดุล ที่ใช้แหล่งจ่ายไฟ 3.0V 3.3V 5.0V
การทำงาน : 8-BIT SHIFT REGISTER

Description :
This device each contains an 8-bit serial-in parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift register and the storage register. The shift register has a direct-overriding clear serial input and serial output pins for cascading. Both the shift register and storage register clocks are positive-edge triggered. If the user wishes to connect both clocks together the shift register state will always be one clock pulse ahead of the storage register.

Features and benefits :
• 8-bit serial input
• 8-bit serial or parallel output
• Storage register with 3-state outputs
• Shift register with direct clear
• 100 MHz (typical) shift out frequency
• Complies with JEDEC standard no. 7A
• Input levels:
– For 74HC595: CMOS level
– For 74HCT595: TTL level
• ESD protection:
