CGS2535V/CGS2535TV
Commercial Quad 1 to 4 Clock Drivers/Industrial Quad
1 to 4 Clock Drivers
General Description
These Clock Generation and Support clock drivers are spe-
cifically designed for driving memory arrays requiring large
fanouts while operating at high speeds.
This device meets the rise and fall time requirements of the
90 and 100 MHz Pentiumprocessors.
The CGS2535 is a non-inverting 4 to 16 driver with CMOS
I/O structures. The CGS2535 specification guarantees
part-to-part skew variation.
Features
n Guaranteed:
— 1.0 ns rise and fall times while driving 12 inches of
50microstrip terminated with 25 pF
— 350 ps pin-to-pin skew (tOSLH and tOSHL)
n 650 ps part-to-part variation on positive or negative
transition @ 5V VCC
n Operates with either 3.3V or 5.0V supply
n Inputs 5V tolerant with VCC in 3.3V range
n Symmetric output current drive: 24 mA IOH/IOL
n Industrial temperature range −40˚C to +85˚C
n Symmetric package orientation
n Large fanout for memory driving applications
n Guaranteed 2 kV ESD protection
n Implemented on National’s ABT family process
n 28-pin PLCC for optimum skew performance

Note 1: The Absolute Maximum Ratings are those values beyond which the
safety of the device cannot be guaranteed. The device should not be oper-
ated at these limits. The parametric values defined in the DC and AC Electri-
cal Characteristics tables are not guaranteed at the absolute maximum rat-
ings. The Recommended Operating Conditions will define the conditions for
actual device operation.

Note 4: Output-to-Output Skew is defined as the absolute value of the difference between the actual propagation delay for any outputs within the same packaged
device and output bank. The specifications apply to any outputs switching in the same direction either LOW to HIGH (tOSLH) or HIGH to LOW (tOSHL).
Note 5: Time high is measured with outputs at 2.0V or above. Time low is measured with outputs at 0.8V or below. Input waveform characteristics for tHigh, tLow mea-
surement: f = 66.67 MHz, duty cycle = 50%.
