74HC670
FEATURES
- Simultaneous and independent read and write operations
- Expandable to almost any word size and bit length
- Output capability: bus driver
- ICC category: MSI GENERAL DESCRIPTION
The 74HC/HCT670 are high-speed Si-gate CMOS devices and are pin patible with low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard no. 7A. The 74HC/HCT670 are 16-bit 3-state register files organized as 4 words of 4 bits each. Separated read and write address inputs (RA, RB and WA, WB) and enable inputs (RE and WE) are available, permitting simultaneous writing into one word location and reading from another location. The 4-bit word to be stored is presented to four data inputs (D0 to D3). The WA and WB inputs determine QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns
74HC/HCT670 the location of the stored word. When the WE input is LOW, the data is entered into the addressed location. The addressed location remains transparent to the data while the WE input...
