These smart power drivers have been designed with BiMOS II logic for improved data entry rates. With a 5 V supply, they will operate to at least 3.3 MHz. At 12 V, higher speeds are possible. Use of these devices with TTL may require the use of appropriate pull-up resistors to ensure an input logic high. All devices can be operated over the ambient temperature range of -40C to +85C. The UCQ5818AF is supplied in a 40-pin plastic dual in-line package with 0.600" (15.24 mm) row spacing. A copper lead frame, reduced supply current requirement, and low output saturation voltage permits operation with minimum junction temperature rise. The `A' package allows all 32 outputs to be operated at -25 mA continuously over the operating temperature range.
