In the first method, • Max tpd of 8 ns at 3.3 V the A input is low, and the B input goes high. In the • Supports Mixed-Mode Voltage Operation on second method, the B input is high, and the A input goes low. In the third method, the A input is low, the All Ports B input is high, and the clear (CLR) input goes high. • Supports Down Translation to VCC The output pulse duration is programmed by selecting • Schmitt-Trigger Circuitry on A and B Inputs for external resistance and capacitance values. The Slow Input Transition Rates external timing capacitor must be connected between • Edge Triggered From Active-High or Active-Low Cext and Rext/Cext (positive) and an external resistor Gated Logic Inputs connected between Rext/Cext and VCC. To obtain • Retriggerable for Very Long Output Pulses, Up to variable pulse durations, connect an external variable 100% Duty Cycle resistance between Rext/Cext and VCC. The output pulse duration also can be reduced by taking CLR • Overriding Clear Terminates Output Pulse low. • Glitch-Free Power-Up Reset on Outputs Pulse triggering occurs at a particular voltage level • Ioff Supports Live Insertion, Partial-Power-Down and is not directly related to the transition time of the Mode, and Back-Drive Protection input pulse. The A and B inputs have Schmitt triggers • Latch-Up Performance Exceeds 100 mA Per with sufficient hysteresis to handle slow input JESD 78, Class II transition rates with jitter-free triggering at the outputs. • ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) Device Information(1) – 200-V Machine Model (A115-A) PART NUMBER PACKAGE BODY SIZE (NOM) – 1000-V Charged-Device Model (C101) SSOP (8) 2.95 mm × 2.80 mm SN74LVC1G123 VSSOP (8) 2.30 mm × 2.00 mm 2 Applications DSBGA (8) 1.91 mm × 0.91 mm • AV Receivers (1) For all available packages, see the orderable addendum at • Blu-ray Players and Home Theaters the end of the data sheet. • DVD Recorders and Players Logic Diagram (Positive Logic) • Desktop PCs or Notebook PCs • Digital Radio and Internet Radio Players • Digital Video Cameras (DVC) • Embedded PCs • GPS: Personal Navigation Devices • Mobile Internet Devices • Network Attached Storage (NAS) • Personal Digital Assistant (PDA) • Server PSU • Solid-State Drive (SSD): Client and Enterprise • Video Analytics Servers • Wireless Headsets, Keyboards, and Mice 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
