Quadruple TTL-to-NMOS Clock Drivers The HD2916, a clock driver for the MOS memory, basically possesses a NAND function. Its Input is a TTL level and its output becomes N MOS clock input level. It operates on two power supplies — Vec (SV) and Vpp (12V). Assuming that a maximum of five units of 4K-bit N MOS memories may be connected, it is designed to drive a load capacity of 200pF at high speeds.

TT ss)])iznng ng gt ae 2G POWER DISSIPATION WITEMS REQUIRING CARE WHEN USING vs. CYCLE TIME THE HD2916 so When measuring or mounting the HD2916, consider 00 1. At the time of “H level output, if a short circuit i eee occurs between the output terminal and the ta er TT other terminal (the GND terminal or input a re terminal), the element will breakdown. z ca a 2. When measuring the input/output characteristic 2 m of the circuit, do not place the input level in the oe vicinity of the threshold voltage (about 1.5V) for i ity tage ( . ftp more than 10 seconds. If this caution is neg- a ee lected, the element may breakdown. Cycle Time tev (ot) @ HITACHI 381
