Features, Applications

The is a register-oriented high-speed 64-bit Read Write Memory organized 4-bits An edgetriggered 4-bit output register allows new input data to be written while previous data is held TRI-STATE outputs are provided for maximum versatility The 'F410 is fully compatible with all TTL families


Edge-triggered output register Typical access time 35 ns TRI-STATE outputs Optimized for register stack operation 18-pin package 9410 replacement

Address Inputs Data Inputs Chip Select Input (Active LOW) Output Enable Input (Active LOW) Write Enable Input (Active LOW) Clock Input (Outputs Change on LOW-to-HIGH Transition) TRI-STATE Outputs

Write Operation When the three control inputs Write Enable (WE) Chip Select (CS) and Clock (CP) are LOW the information on the data inputs D3) is written into the memory location selected by the address inputs A3) If the input data changes while WE CS and CP are LOW the contents of the selected memory location follow these changes provided setup and hold time criteria are met Read Operation Whenever CS is LOW and CP goes from LOW-to-HIGH the contents of the memory location selected by the address inputs (A0 A3) are edge-triggered into the Output Register The (OE) input controls the output buffers When OE is HIGH the four outputs (Q0 Q3) are in a high impedance or OFF state when OE is LOW the outputs are determined by the state of the Output Register
