INTEGRATED CIRCUITS 74LVT374 3.3V Octal D-type flip-flop; positive-edge trigger (3-State) Product specification Supersedes data of 1996 Feb 08 IC23 Data Handbook 1998 Feb 19 Philips Semiconductors Product specification 3.3V Octal D-type flip-flop; positive-edge trigger (3-State) FEATURES 74LVT374 DESCRIPTION • Inputs and outputs on opposite side of package allow easy The 74LVT374 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. interface to microprocessors • 3-State outputs for bus interfacing • Common output enable • TTL input and output switching levels • Input and output interface capability to systems at 5V supply • Bus-hold data inputs eliminate the need for external pull-up The 74LVT374 is an 8-bit, edge triggered register coupled to eight 3-State output buffers. The two sections of the device are controlled independently by the clock (CP) and Output Enable (OE) control gates. The register is fully edge triggered. The state of each D input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop’s Q output. resistors to hold unused inputs • Live insertion/extraction permitted • No bus current loading when output is tied to 5V bus • Power-up 3-State • Power-up reset • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 The 3-State output buffers are designed to drive heavily loaded 3-State buses, MOS memories, or MOS microprocessors. The active-Low Output Enable (OE) controls all eight 3-State buffers independent of the clock operation. When OE is Low, the stored data appears at the outputs. When OE is High, the outputs are in the High-impedance “OFF” state, which means they will neither drive nor load the bus. and 200V per Machine Model QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER TYPICAL UNIT 3.2 3.5 ns tPLH tPHL Propagation delay CP to Qn CL = 50pF; VCC = 3.3V CIN Input capacitance VI = 0V or 3.0V 4 pF COUT Output capacitance Outputs disabled; VI/O = 0V or 3.0V 7 pF ICCZ Total supply current Outputs disabled; VCC = 3.6V 0.13 mA ORDERING INFORMATION TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 20-Pin Plastic SOL PACKAGES –40°C to +85°C 74LVT374 D 74LVT374 D SOT163-1 20-Pin Plastic SSOP Type II –40°C to +85°C 74LVT374 DB 74LVT374 DB SOT339-1 20-Pin Plastic TSSOP Type I –40°C to +85°C 74LVT374 PW 74LVT374PW DH SOT360-1 PIN CONFIGURATION OE 1 PIN DESCRIPTION 20 VCC PIN NUMBER SYMBOL FUNCTION 1 OE 3, 4, 7, 8, 13, 14, 17, 18 Output enable input (active-Low) D0-D7 Data inputs Q0-Q7 Data outputs Q0 2 19 Q7 D0 3 18 D7 D1 4 17 D6 Q1 5 16 Q6 Q2 6 15 Q5 2, 5, 6, 9, 12, 15, 16, 19 D2 7 14 D5 11 CP D3 8 13 D4 10 GND Ground (0V) Q3 9 12 Q4 20 VCC Positive supply voltage 11 CP GND 10 Clock pulse input (active rising edge) SA00110 1998 Feb 19 2 853-1826 18985 Philips Semiconductors Product specification 3.3V Octal D-type flip-flop; positive-edge trigger (3-State) LOGIC SYMBOL 74LVT374 LOGIC SYMBOL (IEEE/IEC) 3 4 7 8 13 14 17 1 18 EN 11 C1 D0 D1 D2 D3 D4 D5 D6 D7 11 1 CP 3 OE 4 5 7 6 Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 2 5 6 9 12 15 16 2 1D 8 19 SA00111 9 13 12 14 15 17 16 18 19 SA00112 FUNCTION TABLE INPUTS H = h = L = l = NC= X = Z = ↑ = ↑ = CP Dn INTERNAL REGISTER OUTPUTS OE L ↑ l L L L ↑ h H H L ↑ X NC NC OPERATING MODE Q0 – Q7 Load and read register Hold H X X NC Z High voltage level High voltage level one set-up time prior to the Low-to-High clock transition Low voltage level Low voltage level one set-up time prior to the Low-to-High clock transition No change Don’t care High impedance “off” state Low-to-High clock transition not a Low-to-High clock transition Disable outputs LOGIC DIAGRAM D0 D1 3 D2 4 D3 7 D4 8 D5 13 D6 14 D7 17 18 D D D D D D D D CP Q CP Q CP Q CP Q CP Q CP Q CP Q CP Q 11 CP 1 OE 2 Q0 5 Q1 6 9 Q2 Q3 12 Q4 15 Q5 16 Q6 19 Q7 SA00113 1998 Feb 19 3 Philips Semiconductors Product specification 3.3V Octal D-type flip-flop; positive-edge trigger (3-State) 74LVT374 ABSOLUTE MAXIMUM RATINGS1, 2 PARAMETER SYMBOL VCC IIK CONDITIONS RATING UNIT –0.5 to +4.6 V –50 mA –0.5 to +7.0 V VO < 0 –50 mA Output in Off or High state –0.5 to +7.0 V Output in Low state 128 Output in High state –64 DC supply voltage DC input diode current VI < 0 voltage3 VI DC input IOK DC output diode current voltage3 VOUT DC output IOUT O DC output current Tstg Storage temperature range mA –65 to 150 °C NOTES: 1.
