These positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic. All have a direct-clear (CLR) input, and the 4ALS175 and 4AS175A feature complementary outputs from each flip-flop.
SN74AS175A Information at the data (D) inputs meeting the setup-time requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When the clock (CLK) input is at either the high or low level, the D-input signal has no effect at the output. These SN74AS175A circuits are fully compatible for use with most TTL circuits.
The SN54ALS174, SN54ALS175, SN54AS174, and SN54AS175A are characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ALS174, SN74ALS175, SN74AS174, and SN74AS175A are characterized for operation from 0°C to 70°C.
