CGS2537TV
CGS2537TV is Industrial Quad Memory Array Clock Drivers manufactured by National Semiconductor.
- Part of the CGS2537V comparator family.
- Part of the CGS2537V comparator family.
Description
These Clock Generation and Support clock drivers are specifically designed for driving memory arrays requiring large fanouts while operating at high speeds.
CGS2537 is a 4 to 16 inverting driver with TTL patible I/Os. This device features the same characteristics of CGS2534 with an added series resistor on the output for ease of termination while reducing the undershoot.
This device has minimum skew specifications of 500 ps pinto-pin as well as a 1 ns specification for part-to-part propagation delay variation.
Features
- Nominal sn output series resistor
- Guaranteed and tested:
- 500 ps pin-to-pin skew (TOSHL and TOHLH)
- Implemented on National's ABT family process
- Output current drive:
- -36 m Al +20 m A IOHIIOL
- Industrial temperature of -40- C to +S5- C
- 2S-pin PLCC for optimum skew performance
- Symmetric package orientation
- Large fanout for memory driving applications
- Guaranteed 2 k V ESD protection
