The 74ACT299MTCX is one member of the 74ACT299 family which is designed as the 8 bit pipo shift register with asynchronous clear that is ideal for low power applications mantaining high speed operation similar to equivalent Bipolar Schottky TTL.
Features of the 74ACT299MTCX are:(1)highspeed: fMAX = 170MHz(typ.) at Vcc =5V; (2)lowpowerdissipation: Icc =8 mA (max.) at TA =25 ; (3)highnoiseimm-unity: VNIH=VNIL =28%Vcc (min.); (4)50W transmissionlinedriving capability; (5)symmetrical output impedance: |IOH| = IOL = 24mA (min); (6)balancedpro-pagationdelays: tPLH @ tPHL; (7)operatingvoltagerange: Vcc (opr)= 2V to 6V; (8)pinandfunction compatiblewith 74 series299; (9)improvedlatch-up immunity.
The absolute maximum ratings of the 74ACT299MTCX can be summarized as:(1)supply voltage:-0.5 to +7 V;(2)DC input voltage:-0.5 to Vcc+0.5 V;(3)DC output voltage:-0.5 to Vcc+0.5 V;(4)DC input diode current:±20 mA;(5)DC output diode current:±20 mA;(6)DC output current:±50 mA;(7)DC Vcc or ground current:±400 mA;(8)storage temperature:-65 to +150 ;(9)lead temperature (10 sec):300 .

74ACT299PC General Description
The AC/ACT299 is an 8-bit universal shift/storage register with 3-STATE outputs. Four modes of operation are possible: hold (store), shift left, shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins. Additional outputs are provided for flip-flops Q0, Q7 to allow easy serial cascading. A separate active LOW Master Reset is used to reset the register.
