TSSOP ORDER CODES PACKAGE TSSOP TUBE T&R PIN CONNECTION bs O DESCRIPTION The 74VHCT16374A is an advanced high-speed CMOS 16 D-TYPE FLIP FLOP with 3 STATE OUTPUTS NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. These 16 bit D-TYPE flip-flop is controlled by two clock inputs (CK) and two output enable inputs (nOE). The device can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs. While the (OE) input is low, the outputs will be in a normal logic state (high or low logic level); while OE is high, the outputs will be in a high impedance state. The output control does not affect the internal operation of flip-flops; that is, the old data can be retained or the new data can be entered even while the outputs are off. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. let o Pr e du o (s) ct so Ob - te le ro P uc d 74VHCT16374ATTR s) t( February 2003 1/10 74VHCT16374A INPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No 1 2, 3, 5, 6, 8, 9, 11, 12 13, 14, 16, 17, 19, 20, 22, 23 24 SYMBOL 1OE 1Q0 to 1Q7 2Q0 to 2Q7 2OE NAME AND FUNCTION 3 State Output Enable Input (Active LOW) 3-State Outputs 3-State Outputs IEC LOGIC SYMBOLS 3 State Output Enable Input (Active LOW) 25 2CK Clock Input (LOW-to-HIGH Edge Trigger) 36, 35, 33, 32, 2D0 to 2D7 Data Inputs 30, 29, 27, 26 47, 46, 44, 43, 1D0 to 1D7 Data Inputs 41, 40, 38, 37 48 1CK Clock Input (LOW-to-HIGH Edge Trigger) 4, 10, 15, 21, GND Ground (0V) 28, 34, 39, 45 7, 18, 31, 42 VCC Positive Supply Voltage TRUTH TABLE INPUTS OE O bs L L L H let o CK X Pr e du o D X X L H (s) ct Q Z so Ob - te le ro P uc d s) t( OUTPUTS NO CHANGE L H X : Don't Care Z : High Impedance 2/10 74VHCT16374A LOGIC DIAGRAM This logic diagram has not to be used to estimate propagation delays ABSOLUTE MAXIMUM RATINGS Symbol VCC VI VO IIK IOK IO Supply Voltage DC Input Voltage DC Output Voltage DC Input Diode Current DC Output Diode Current DC Output Current Parameter ICC or IGND DC VCC or Ground Current Tstg Storage Temperature TL Lead Temperature (10 sec) Absolute Maximum Ratings are those values beyond which damage to the device may occur.
