6 / 10 page Philips Semiconductors Product specification 74LVC16373A/ 74LVCH16373A 16-bit D-type transparent latch with 5 Volt tolerant inputs/outputs (3-State) 1998 Mar 17 6 DC ELECTRICAL CHARACTERISTICS (Continued) Over recommended operating conditions voltages are referenced to GND (ground = 0V) LIMITS SYMBOL PARAMETER TEST CONDITIONS Temp = -40 °C to +85°C UNIT MIN TYP1 MAX IBHL Bus hold LOW sustaining current VCC = 3.0V; VI = 0.8V2, 3, 4 75 µA IBHH Bus hold HIGH sustaining current VCC = 3.0V; VI = 2.0V2, 3, 4 –75 µA IBHLO Bus hold LOW overdrive current VCC = 3.6V2, 3, 5 500 µA IBHHO Bus hold HIGH overdrive current VCC = 3.6V2, 3, 5 –500 µA NOTES: 1. All typical values are at VCC = 3.3V and Tamb = 25°C. 2. Valid for data inputs of bus hold parts (LVCH16-A) only. 3. For data inputs only, control inputs do not have a bus hold circuit. 4. The specified sustaining current at the data input holds the input below the specified VI level. 5. The specified overdrive current at the data input forces the data input to the opposite logic input state. 6. For bus hold parts, the bus hold circuit is switched off when Vi exceeds VCC allowing 5.5V on the input terminal. AC CHARACTERISTICS GND = 0V; tR = tF = 2.5ns; CL = 50pF; RL = 500Ω; Tamb = –40°C to +85°C.

VOL and VOH are the typical output voltage drop that occur with the output load. VX = VOL + 0.3V at VCC w 2.7V; VX = VOL + 0.1 VCC at VCC t 2.7V VY = VOH –0.3V at VCC w 2.7V; VY = VOH – 0.1 VCC at VCC t 2.7V SW00070 Dn INPUT VM tPHL tPLH VOL VI VM GND VOH Qn OUTPUT VM Waveform 1.
