SN74LVTH273PWLE

The SN74LVTH273PWLE is designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment. The device is positive-edge-triggered flip-flops with a direct-clear 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 pulse.

The following is about the absolute maximum ratings of SN74LVTH273PWLE: (1)Supply voltage range, VCC: -0.5 V to 4.6 V; (2)Input voltage range, VI: -0.5 V to 7 V; (3)Voltage range applied to any output in the power-off state, VO : -0.5 V to 7 V; (4)Voltage range applied to any output in the high state, VO: -0.5 V to VCC + 0.5 V; (5)Current into any output in the low state, IO: 128 mA; (6)Current into any output in the high state, IO: 64 mA; (7)Input clamp current, IIK (VI < 0): -50 mA; (8)Output clamp current, IOK (VO < 0): -50 mA; (9)Package thermal impedance, JA: DB package 70°C/W, DW package 58°C/W, NS package 60C/W, package 83°C/W; (10)Storage temperature range, Tstg: -65°C to 150°C.

The electrical characteristics of the SN74LVTH273PWLE are: (1)VIK: -1.2V max at VCC=2.7V, II=-18mA; (2)VOH: VCC-0.2V max at VCC=2.7V to 3.6V, IOH=-100A; (3)VOL: 0.2V max at VCC=2.7V, IOL=100A; (4)II: ±1A max at VI=VCC or GND, VCC=3.6V; (5)Ioff: ±100A max at VI or VO=0 to 4.5V, VCC=0; (6ICC: 0.19mA max at VI=VCC or GND, VCC=3.6V, IO=0.
