MC10H646

MOTOROLA SEMICONDUCTOR TECHNICAL DATA PECL/TTL-TTL 1:8 Clock Distribution Chip MC10H646 MC100H646 The MC10H/100H646 is a single supply, low skew translating 1:8 clock driver. Devices in the Motorola H600 translator series utilize the 28–lead PLCC for optimal power pinning, signal flow through and electrical performance. The single supply H646 is similar to the H643, which is a dual supply 1:8 version of the same function. PECL/TTL–TTL Version of Popular ECLinPS™ E111 Low Skew Guaranteed Skew Spec Tri–State Enable Differential Internal Design VBB Output Single Supply Extra TTL and ECL Power/Ground Pins Matched High and Low Output Impedance Meets Specifications Required to Drive the Pentium™ Microprocessor PENTIUM MICROPROCESSOR PECL/TTL–TTL CLOCK DRIVER The H646 was designed specifically to drive series terminated transmission lines. Special techniques were used to match the HIGH and LOW output impedances to about 7ohms. This simp...
