6.6 Switching Characteristics

Unless otherwise noted, VDD = V_EN = 4.5 V to 18 V, T_A = T_J = –40°C to 125°C, 1-µF capacitor from VDD to GND, no load on the output. Typical condition specifications are at 25°C ⁽¹⁾.

PARAMETER		TEST CONDITIONS	TYP	MAX	UNIT
t_Rx	Rise time	C_LOAD = 1.8 nF, 10% to 90%, Vin = 0 V – 5 V	11	25	ns
t_Fx	Fall time	C_LOAD = 1.8 nF, 90% to 10%, Vin = 0 V – 5V	7	23	ns
t_D1x	Turn-on propagation delay	C_LOAD = 1.8 nF, V_{INx_H} of the input rise to 10% of output rise, Vin = 0 V –5 V, Fsw = 500 kHz, 50% duty cycle	18	33	ns
t_D2x	Turn-off propagation delay	C_LOAD = 1.8 nF, V_{INx_L} of the input fall to 90% of output fall, Vin = 0 V – 5 V, VDD= 5V -18V, Fsw = 500 kHz, 50% duty cycle	30	50	ns
t_D3x	Enable propagation delay	C_LOAD = 1.8 nF, V_{ENx_H} of the enable rise to 10% of output rise, Vin = 0 V – 5 V, Fsw = 500 kHz, 50% duty cycle	19	31	ns
t_D4x	Disable propagation delay	C_LOAD = 1.8 nF, V_{ENx_L} of the enable fall to 90% of output fall, Vin = 0 V – 5 V, Fsw = 500 kHz, 50% duty cycle	24	52	ns
t_M	Delay matching between two channels	C_LOAD = 1.8 nF, Vin = 0 V – 5 V, Fsw = 500 kHz, 50% duty cycle, INA = INB, \|t_RA – t_RB\|, \|t_FA – t_FB\|	1	5	ns
