DESCRIPTION
 The CAT28C512/513 is a fast,low power, 5V-only CMOS parallel EEPROM organized as 64K x 8-bits.
It requires a simple interface for in-system programming.
On-chip address and data latches, self-timed write cycle with auto-clear and VCC power up/down write protection eliminate additional timing and protection hardware.
DATA Polling and Toggle status bits signal the start and end of the self-timed write cycle.
Additionally, the CAT28C512/513 features hardware and software write protection.
The CAT28C512/513 is manufactured using Catalyst’s advanced CMOS floating gate technology.
It is designed to endure 100,000 program/erase cycles and has a data retention of 100 years.
The device is available in JEDEC approved 32-pin DIP, PLCC and TSOP packages.

Description
The MC74HC595A consists of an 8–bit shift register and an 8–bit D–type latch with three–state parallel outputs. The shift register accepts serial data and provides a serial output. The shift register also provides parallel data to the 8–bit latch. The shift register and latch have independent clock inputs. This device also has an asynchronous reset for the shift register.
The HC595A directly interfaces with the SPI serial data port on CMOS MPUs and MCUs.

• Output Drive Capability: 15 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 mA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard No. 7A
• Chip Complexity: 328 FETs or 82 Equivalent Gates
• Improvements over HC595
  - Improved Propagation Delays
  - 50% Lower Quiescent Power
  - Improved Input Noise and Latchup Immunity
