description

These positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic. All have a

direct-clear (CLR) input. The ’ALS175 and ’AS175B feature complementary outputs from each flip-flop.

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 circuits are fully compatible for use with most TTL circuits.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

On products compliant to MIL-PRF-38535, all parameters are tested

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

unless otherwise noted. On all other products, production

testing of all parameters.

processing does not necessarily include testing of all parameters.
