INTEGRATED CIRCUITS GTL2010 10-bit GTL Processor Voltage Clamp Product specification 1999 Apr 05 Philips Semiconductors Product specification 10-bit GTL Processor Voltage Clamp FEATURES GTL2010 PIN CONFIGURATION • Direct interface with TTL level • 6.5Ω ON-state connection between port Sn and Dn GND 1 24 GREF SREF 2 23 DREF S1 3 22 D1 S2 4 21 D2 S3 5 20 D3 S4 6 19 D4 S5 7 DESCRIPTION The GTL2010 is a high speed 10-bit voltage clamp. The low ON-state resistance of the clamp allows connections to be made with minimal propagation delay. 18 D5 S6 8 17 D6 S7 9 16 D7 S8 10 15 D8 S9 11 14 D9 S10 12 13 D10 The device is organized as one 10-bit voltage clamp. When S or D is low, the clamp is in the ON–state and a low resistance connection exists between the S and D ports. When S port and D port are high, the clamp is in the OFF-state and a very high impedance exists between the S and D ports. When port D is high, the voltage on the S port is clamped to the applied reference voltage on the GREF port.

Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
