description
These octal positive-edge-triggered flip-flops
utilize TTL circuitry to implement D-type flip-flop
logic with a direct-clear (CLR) input.
Information at the data (D) inputs meeting the
setup-time requirements is transferred to the
Q outputs on the positive-going edge of the clock
(CLK) pulse. Clock triggering occurs at a particular
voltage level and is not directly related to the
transition time of the positive-going pulse. When
CLK is at either the high or low level, the D input
signal has no effect at the output.
The SN54ALS273 is characterized for operation
over the full military temperature range of –55
°
C
to 125
°
C. The SN74ALS273 is characterized for
operation from 0
°
C to 70
°
C.
